Two-Digit Addition: Regrouping Quiz
 

Two-Digit Addition: Regrouping QuizOnline version

Test regrouping rules in two-digit addition.

by Nehal Kamal
1

You align digits by columns from left to right.

2

If the ones sum is 9, you still carry 1.

3

Regrouping may produce a carry into the hundreds when adding two two-digit numbers.

4

In two-digit addition, the tens place can’t cause a carry.

5

Regrouping is never needed when adding two two-digit numbers.

6

The carry is written in the hundreds column for all two-digit additions.

7

A carry from the ones place increases the tens place by 1.

8

The final answer can have three digits (e.g., 99 + 99 = 198).

9

Regrouping occurs from ones to tens, not from tens to ones.

10

If ones sum is 10 or more, you write the ones digit and carry 1 to tens.
