In 3^{th} Grade Subtraction Worksheet we will solve how to subtract 3-digit numbers by expansion,
subtraction of 3-digit numbers without regrouping, subtraction of 3-digit
numbers with regrouping, properties of subtraction, estimating the difference
and word problems on 3-digit subtraction.

Subtract by Expansion:

We can use the place value of the digits to subtract quickly, without using a paper and pen. For example subtract 119 from 569.

569 - 119 = 500 + 60 + 9 - 100 + 10 + 9

= 500 - 100 + 60 - 10 + 9 - 9

= 400 + 50 + 0

= 450

**2.** 600 – 300 = ………..

**3.** 785 – 0 = ………..

**4.** ……….. – 300 = 600
