Find the answer to the following
equation. 28 subtract six equals what.
In this question, we have to
subtract a one-digit number, which is the number six, from a two-digit number,
28. And we have to use column
subtraction. When we use column subtraction, we
always start by subtracting in the ones column. Number 28 has eight ones, and we
need to subtract six. What is eight subtract six? It’s two. Six plus two is eight. Eight subtract six is two. Now all we need to do is subtract
in the tens column. 28 has two 10s and six has no
10s. Two 10s subtract no 10s leaves us
with two 10s. 28 subtract six equals 22. We found the answer using column
subtraction. First, we subtracted in the ones
column. Then we subtracted in the tens
column to give us the answer 22.
