Adding and Subtracting Two-Digit Numbers
Learning Objective
I can add and subtract two-digit numbers by breaking them into tens and ones.
Key Concepts
In expanded form subtraction, you first write each number as the sum of its tens and ones.
When subtracting, if the digit you are subtracting is larger than the digit you are subtracting from, you need to borrow from the next place value.
After borrowing and subtracting, you add the results from each place value to find the final answer.
