Practice Multi-Digit Addition and Subtraction in Math

Use these practice problems to test your method after reviewing the concept explanation and worked examples.

Quick Recap

Adding and subtracting numbers with three or more digits using the standard algorithm, which involves regrouping (carrying) in addition and borrowing in subtraction.

Imagine stacking blocks in columns for ones, tens, and hundreds. When the ones column adds up to more than 9, you bundle 10 ones into 1 ten and carry it over—just like exchanging 10 pennies for a dime.

Example 1

easy
Calculate \(347 + 256\) using column addition.

Example 2

medium
Calculate \(803 - 457\) using column subtraction with borrowing.

Example 3

easy
Calculate \(528 + 364\).

Example 4

medium
A school library has 1,250 books. They donate 387 books. How many books remain?
