Step 3.

Check by adding the answer to the bottom number.

53 + 25 = 78.

d.

symbol x. The answer to multiplication problems is called the product. To

find the product write the numbers in columns under each other, as in

addition, and proceed as shown in Example 3.

EXAMPLE 3.

Multiply 25 by 3.

Step 1.

Multiply the digits in the ones

position. 3 x 5 = 15. Write the

5 under the ones position and carry

the 1 to the tens position.

Step 2.

Multiply the digit 2 in the tens

column by the digit 3 and add the

digit 1 carried over to the tens

column. 2 x 3 = 6 + 1 = 7.

Step 3.

Check by dividing the product 75

by 3 as explained in the succeeding

paragraph.

e.

A requirement for division is indicated by the symbol ƒ.

The answer to division problems is called the quotient.

To find the

quotient, proceed as shown in Example 4.

EXAMPLE 4.

Divide 75 by 3.

Step 1.

Divide the digit 7 by the

divisor 3. 7 + 3 = 2. Write the

2 above the 7 in the tens position.

Step 2.

Multiply the divisor 3 by the

digit 2. 3 x 2 = 6. Write the 6

under the 7.
