# Subtracting 1 Worksheets || Grade 1 Math

In this post we will learn subtraction of any given number with 1. After that we will solve some questions related to the concept.

The concept of subtraction is extremely important for our academic and practical life. So its important for the kids to fully understand the concept and practice it sufficiently so that it gets engrained in your mind.

Subtraction with 1

If we subtract any number with 1, we will get the previous smaller number.

For Example:
⟹ 13 – 1 = 12

In the above number line, we start from number 13. As we have to subtract the number by 1, we take 1 jump towards to reach 12.

Hence when we subtract number 13 with 1, we get previous smaller number 12.

We have understood the basic concept of subtraction with 1. Now see the table below where we have calculated subtraction of 1 with numbers 1 to 20

Conclusion: On subtracting number 1, we will get previous smaller number
