What this worksheet covers

Grade: Grade 4 (Elementary School)
Topic: Adding and Subtracting Decimals
Worksheet: Subtraction

Fill in the Blank supplies the box and Word Problems asks for the quantity remaining. On the expression side, Basics (Column Calculation) matches the digit counts, Different Number of Digits (Column Calculation) differs in how deep the two numbers run below the point, and Up to 3 Decimal Places (Column Calculation) keeps the breaking going, with the same range appearing in single-line working.

Add the number taken away back onto the answer found and the original number comes back exactly. This check bites where a place was subtracted within itself, larger digit from smaller, instead of breaking from above. An added-back figure that swells past the original means the break was skipped. The more places run on, the further back the discrepancy is left.

In Adding and Subtracting 3 Numbers three numbers stand in one expression and adding and subtracting are mixed together. What Addition supplied was the touch of lining places up vertically, and this lesson lays the borrowing on top of it.
