Subtraction: subtract 1-digit numbers from 2-digit numbers and 2-digit numbers from 2-digit numbers with Regrouping
Here, we will learn how to subtract 1-digit numbers from 2-digit numbers and 2-digit numbers from 2-digit numbers with regrouping. Note that the digits in the tens and ones places of the minuend are smaller than the digits in the tens and ones places of the subtrahend. Let’s get started.
Let us
subtract 7 from 46
Here, 6
< 7.
So,
46 = 4
tens + 6 ones
= 3 tens + 16 ones
7 = 0 tens + 7 ones
(-)
3 tens + 9 ones = 39

Let us subtract 47 from 75
Here, 5
< 7
75 = 7
tens + 5 ones
= 6 tens + 15 ones
47 = 4
tens +7 ones
(-) 2 tens + 8 ones = 28
