📘 Two-Digit Addition Lesson

Learn how to add numbers with two digits (tens & ones) step by step!

📖 Introduction

Two-digit addition means we’re adding numbers from 10 to 99. Each number has a tens place and a ones place. When we add them, we start with the ones. If the sum is 10 or greater, we carry (regroup) the extra ten into the tens place.

🧩 Step-by-Step Example

Example: 47 + 36

  1. Line up the numbers by place value: 
       47
+ 36
  2. Add the ones: 7 + 6 = 13 → Write 3, carry the 1 to the tens.
  3. Add the tens: 4 + 3 = 7, plus the carried 1 = 8.
  4. Final Answer: 83
