Today At The Test, the BBC's Test cricket highlights programme is presented by Isa Guha alongside commentators, Michael Vaughan, Phil Tufnell, Ebony Rainford-Brent, Alastair Cook and James Anderson. On 30 June 2017 it was announced that live cricket would be returning to BBC TV for the first time in 21 years. The BBC shows highlights of the Premier League on Match of the Day which is hosted by Kelly Cates, Mark Chapman, and Gabby Logan.
- Previously shown as part of Grandstand, when the BBC regained the rights coverage was aired within a special Boat Race programme with Clare Balding hosted the coverage and, apart from in 2012, Andrew Cotter was the commentator.
- National commentary on the National Hockey League, Elite Ice Hockey League, Champions Hockey League and the IIHF World Championships
- For basic calculators, the speed can vary from a few hundred hertz to the kilohertz range.
- The BBC has the rights to show coverage of each Diamond League meeting on the red button, with the two British rounds and final two meetings live on BBC Two and selected meetings on BBC Three.
- Although machines capable of performing all four arithmetic functions existed prior to the 19th century, the refinement of manufacturing and fabrication processes during the eve of the industrial revolution made large scale production of more compact and modern units possible.
- However, CI’s more successful calculators involved a line of construction calculators, which evolved and expanded in the 1990s to present.
- There were great efforts to put the logic required for a calculator into fewer and fewer integrated circuits (chips) and calculator electronics was one of the leading edges of semiconductor development.

Reports every 15 minutes plus wicket flashes on England Test, ODI and T20 matches In October 2025 it was announced that coverage from the 2026 event will move to Channel 4.
The first calculator capable of symbolic computing was the HP-28C, released in 1987. Many firms saw that there were good profits to be made in the calculator business with the margin on such high prices. The high price was due to their construction requiring many mechanical and electronic components which were costly to produce, and production runs that were too small to exploit economies of scale. The advantage of LCDs is that they are passive light modulators reflecting light, which require much less power than light-emitting displays such as LEDs or VFDs. An extension of one glass plate needed for the liquid crystal display was used as a substrate to mount the needed chips based on a new hybrid technology.

From the 2009 season, more coverage became available on qualifying and race days again through the use of the Red Button service. The BBC showed all MotoGP races, with all qualifying sessions live via the BBC Red Button. In 2003, the BBC won the rights to the MotoGP World Championship. Murray Walker contributed to coverage across the BBC for over sixty years and triple world champion and Mercedes driver Lewis Hamilton has a blog on BBC's website. The BBC always showed the British Grand Prix and the final race live. The BBC gave up the rights to the British Touring Car Championship at the end of 2001, with the rights eventually being picked up by ITV.
Beginning at the 2018 Winter Olympics, the BBC entered into sub-licensing agreements with Discovery Communications, the pan-European rightsholder of the Olympics for 2018 through 2024. The BBC's current rights deal lasts through the 2032 Summer Olympics. The BBC's Super League Show shows weekly highlights of the Super League, Magic Weekend, Super 8s and the Grand Final. Coverage is hosted by Mark Chapman and Tanya Arnold with commentary from Dave Woods, Jonathan Davies and Brian Noble. The BBC holds joint rights to the Six Nations championship in the UK with ITV Sport until 2029. For most recent Wimbledon tournament in 2021, Gigi Salmon and Tony Livesey hosted full coverage on Radio 5 Live, with expert analysis from Marion Bartoli, Pat Cash, Laura Robson, Leon Smith, Chanda Rubin, Annabel Croft, Miles Maclagan, Mark Woodforde and Jeff Tarango.

In 1971, Pico Electronics and General Instrument also introduced their first collaboration in ICs, a full single chip calculator IC orionsbet casino no deposit bonus for the Monroe Royal Digital III calculator. However, integrated circuit development efforts culminated in early 1971 with the introduction of the first "calculator on a chip", the MK6010 by Mostek, followed by Texas Instruments later in the year. It weighed 1.59 pounds (721 grams), had a vacuum fluorescent display, rechargeable NiCad batteries, and initially sold for US$395. The first handheld calculator was a 1967 prototype called Cal Tech, whose development was led by Jack Kilby at Texas Instruments in a research project to produce a portable calculator. By 1970, a calculator could be made using just a few chips of low power consumption, allowing portable models powered from rechargeable batteries.
BBC Sport – News & Live Scores
- The BBC shows live coverage of the Challenge Cup including both semi-finals and the final, the Four Nations and the Rugby League World Cup.
- Sometimes significant design effort is needed to fit all the desired functions in the limited memory space available in the calculator chip, with acceptable calculation time.
- The new look gave more prominence to live sports, programmes and events as well as news on the individual teams.
- Since 2016, Sky Sports has exclusive UK rights to The Open with the BBC showing a two-hour highlights programme every night.
- The BBC also broadcasts live coverage of the FA Cup and will do so until 2026.
In the United States, many math educators and boards of education have enthusiastically endorsed the National Council of Teachers of Mathematics (NCTM) standards and actively promoted the use of classroom calculators from kindergarten through high school. As a result, the use of calculators is to be included as part of a review of the Curriculum. In December 2011 the UK's Minister of State for Schools, Nick Gibb, voiced concern that children can become "too dependent" on the use of calculators.

Pascal's calculator could add and subtract two numbers directly and thus, if the tedium could be borne, multiply and divide by repetition. The Renaissance saw the invention of the mechanical calculator by Wilhelm Schickard in 1623, and later by Blaise Pascal in 1642. If the numeric quantity were stored and manipulated as pure binary, interfacing to such a display would require complex circuitry.
U.S. semiconductor manufacturers led the world in large scale integration (LSI) semiconductor development, squeezing more and more functions into individual integrated circuits. The first Soviet programmable desktop calculator ISKRA 123, powered by the power grid, was released at the start of the 1970s. During this era, the absence of the conditional branch was sometimes used to distinguish a programmable calculator from a computer. A large, printing, desk-top unit, with an attached floor-standing logic tower, it could be programmed to perform many computer-like functions.
Until 2015, the BBC's coverage of The Open Championships was extensive with coverage broadcast live and uninterrupted on BBC Two between 9 am and 8 pm on Thursday and Friday and on BBC One on Saturday and Sunday. The BBC has the rights to show coverage of each Diamond League meeting on the red button, with the two British rounds and final two meetings live on BBC Two and selected meetings on BBC Three. For the 2012 Olympics in London the BBC had three stations showing live coverage of the games. The BBC holds the exclusive terrestrial rights to show Summer Olympic Games and Winter Olympic Games and has shown live coverage of every Summer Olympics since 1960.
Precursors to the electronic calculator
For example, there are scientific calculators, which include trigonometric and statistical calculations. In addition to general-purpose calculators, there are those designed for specific markets. A calculator is typically a portable electronic device used to perform calculations, ranging from basic arithmetic to complex mathematics. You can see the current math calculations in a smaller display that is below the main display of the calculator. BBC show one match a week from the WSL and the Bundesliga and has 7 live games from the Women's Champions League.
Former commentators were Harry Carpenter and after his retirement, Barry Davies who described the action until the BBC lost the rights after the 2004 event. With the exception of between 2005 and 2009, when the coverage was on ITV, the BBC has shown the event since 1938. The BBC also covered the BDO Winmau World Masters from 2001 to 2010 but this coverage was lost to ESPN. The BBC then lost the TV rights to the event to Channel 4 after they made a £10 million bid. Jennie Gow replaced Perry for 2010, but from 2011 former pitlane reporter Matt Roberts became host, alongside the original and unchanged commentary team of Charlie Cox and Steve Parrish.
