# Subtract 2 Digit Number from 2 Digit within 100

- 2nd Grade Math

In the two preceding worksheets, students subtract ones and tens (separately) from a 2 digit number. Following on, 2 Digit Subtraction Worksheet involves subtracting a 2 digit number from another 2 digit number, without any need for regrouping (decomposing tens to subtract). It starts with subtraction using models, reinforcing the concept of subtracting tens and subtracting ones to find the difference.
