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.
