Find the value of the following: 26
subtract 15.

In this question, we have to
subtract a two-digit number from a two-digit number using column subtraction. When we use the column method, we
always subtract the ones first. The number 26 has six ones, and 15
has five ones. We need to subtract five from
six. What is six take away five? It’s one. So we can write a one in the ones
column. We had six ones. We subtracted five. We’ve got one left.

Now we can subtract in the tens
column. We know the number 26 has two 10s
and the number 15 has one 10. So we need to subtract our one 10
from our two 10s. What is two 10s take away one
10? It’s one 10. So 26 take away 15 is 11.

First, we subtracted the ones. Then, we subtracted the tens. 26 take away 15 equals 11.
