# Multiply using partial products

The 5 steps below will quickly show you how to multiply using partial products. Here, we will do the multiplication for a two-digit number by another two-digit number.

Multiply 26 by 45

If you multiply a two-digit number by another two-digit number, you will have 4 partial products.

 Step 1Multiply the tens by the tens.  ------------------------->20 x 4 tens = 80 tens or 800 Tens   Ones                               4   5                         x     2   6              ____________                   8   0   0
 Step 2Multiply the ones by the tens.  ------------------------->5 ones x 20 = 100 ones 1   0   0
 Step 3Multiply the tens by the ones.  ------------------------->4 tens x 6  = 24 tens = 240 2   4   0
 Step 4Multiply the ones by the ones.  ------------------------->5 x 6 ones  = 30 ones = 30 +        3   0
 Step 5Add the partial products.  ------------------------->800 + 100 + 240 + 30 = 1170 _____________________                1  1   7   0

So 26 x 45 = 1170
