So far, on this week’s math kick, we’ve looked at Algebra, variables, and constants. Today, we continue with an operation.

Turning, once again to MathIsFun.com, we find that an operation is defined as “a mathematical process,” with the most common being to multiply, divide, add, and subtract.

In our example, Y – 5 = 10, the operation is to subtract 5 from the value of Y.

The “-“, or minus sign, is an operator, which MathIsFun.com explains as “a symbol (such as +, −, ×, etc) that shows an operation.”

In our example, Y – 5 = 10, “-” is the operator, telling us that 5 is to be subtracted from the value of 5 Y.
