Multiplication is a way to add a number to itself a certain number of times.
In a multiplication sentence, the numbers that are multiplied are called
factors, and the answer is called the
product.
3 | × | 5 | = | 15 |
factor | × | factor | = | product |
Use repeated addition to find the product.
3 × 5 is the same as three 5's added together.
Division is a way to separate a number of objects into equal groups.
In a division sentence, the first number is called the
dividend, the second number is called the
divisor, and the answer is called the
quotient.
15 | ÷ | 5 | = | 3 |
dividend | ÷ | divisor | = | quotient |
Use repeated subtraction to find the quotient.
Subtract 9 from 18 until the difference is zero.
Nine subtracted from 18 two times equals zero.
So, the quotient is 2.
