Somewhere around middle school, you learned about squaring numbers and the inverse, finding the square root of a number, but a little reminder can't hurt. You square a number when you multiply it by ...

Microsoft Excel is a powerful tool for carrying out complex calculations. If you work on Excel, then you might come across performing mathematical operations almost every day. Sometimes, we face ...

Roots are the opposite of powers. As 2 squared is 4, then a square root of 4 must be 2. \(2^2 = 4\). Reversing this gives \(\sqrt{4} = 2\). To find square roots or cube roots, work backwards from ...

The Mathematics Teacher (MT), an official journal of the National Council of Teachers of Mathematics, is devoted to improving mathematics instruction from grade 8-14 and supporting teacher education ...

Roots are the reverse of powers. For example, a square root is the reverse of a square number. So \(5^2 = 25\) and \(\sqrt{25} = 5\) A cube root is the reverse of a cube number. Write 40 as a product ...

A computer made from strands of DNA in a test tube can calculate the square root of numbers up to 900. Chunlei Guo at the University of Rochester in New York state and colleagues developed a computer ...

DNA is like software, telling our cellular and molecular hardware what to do – except it uses biochemical reactions rather than the electronic circuitry of computers we’re used to. Now, researchers ...

A new DNA computer calculates square roots of perfect squares up to 900. Like quantum computers, DNA computers are an exciting frontier of post-silicon computing. Where previous examples were up to 4 ...

May is almost here, bringing warmer weather and various holidays, such as Mother's Day, Memorial Day and Cinco de Mayo. While Cinco de Mayo is the most popular reason to celebrate May 5, this year, ...
