When a number is squared in math, it means it's been multiplied by itself. For example, two squared is two times two, or four; and 10 squared is 10 times 10, or 100. When a number is squared, it is written as that number (the base) to the second power.
Know MoreWhether the base is positive or negative, the base squared is always positive. Two positive numbers multiplied together yield a positive product, and two negative numbers multiplied together always make a positive number as well. A square root of a number is the number which, when multiplied by itself, yields the square. For example, the square root of 25 is either five or negative five because either of those numbers multiplied by itself yields 25.

The operation 4 x 4, for example, is written exponentially as 4^2.
Full Answer >In math, a ray is part of a line that has an endpoint at its starting point and extends in a certain direction into infinity. Drawing a ray involves placing a line with one endpoint and an arrow point on the other end. To name a ray, the convention is to use the letter at the starting point followed by a letter near the arrow point.
Full Answer >In math, the definition of an exponent is a numerical notation that indicates the number of times a number is to be multiplied by itself. The exponent is written as a small number in superscript following the number to be multiplied.
Full Answer >To square a number, simply multiply the number by itself. For example, 3 squared would literally be 3 multiplied by 3, which is 9. When a number is squared, it is typically denoted with a small two written in the top right corner of the number or with a "^" sign after the number itself, like 3^2.
