Subtraction By Grouping Tens And Ones

Let us subtract 65 – 24.

We know that 65 is We know that 24 is

6 tens and 5 ones 2 tens and 4 ones

So, 65 – 24 = 6 tens + 5 ones – 2 tens + 4 ones

= 6 – 2 tens + 5 – 4 ones

= 4 tens + 1 one = 41

A. Subtract by Grouping tens and ones.

1. 49 – 22 = tens + ones – tens + ones

= – tens + – ones

= tens + ones =

2. 74 – 32 = tens + ones – tens + ones

= – tens + – ones

= tens + ones =
