Answer:

Here is a step-by-step process for multiplying two 2-digit numbers:

Example problem: 24 x 36

Write the two numbers one on top of the other, lining up the ones digits in the right column and the tens digits in the left column:

24

x 36

Multiply the ones digits together (4 x 6) and write the result under the line, in the ones column:

24

x 36

24

Multiply the tens digit of the bottom number by the ones digit of the top number (3 x 4) and write the result in the tens column, leaving a space for any carry-over digit:

24

x 36

144

Repeat step 3, but this time multiply the top digit by the bottom digit:

24

x 36

144

72

Add up the two partial products (the numbers you wrote under the line in steps 2 and 4):

24

x 36

144

72

864

The final answer is 864.
