# How to Multiply

The rules of multiplication extend beyond multiplying 2 whole numbers. Here are some of the others.

### Instructions

- Step 1:
**Multiply fractions**Handle fractions by multiplying the numerators and denominators. Place the product of the numerators over that of the denominators and simplify. - Step 2:
**Multiply polynomials**Handle polynomials by multiplying each term in the 2nd polynomial by each term in the first one. Combine like terms. - Step 3:
**Multiply signed numbers**Multiply signed numbers the same way you multiply unsigned ones, but take into account the signs. - TIP: If both numbers are negative or positive, the product is positive. If 1 number is positive and the other is negative, the product is negative.
- Step 4:
**Handle exponents**Multiply 2 terms in the same variable by adding their exponents. - Step 5:
**Multiply square roots**Handle 2 terms involving the square roots of positive numbers by multiplying the 2 numbers under the square root sign. Multiplication is as simple as that unless, of course, you are like the snake who claimed he couldn't multiply because he was an adder. - FACT: The concept of zero was in use in India five centuries before it made its way to Europe.
