What this printable includes
Practice twelve addition and subtraction calculations with decimals to hundredths. The page combines the two operations so learners must read each sign, while the answer image and text key provide exact results. All subtraction results on this sheet are nonnegative.
How to use the page
Align decimal points when setting up a written calculation. Whole-number, tenths and hundredths positions must stay in matching columns. A trailing zero can make place values easier to see without changing the value. For example, two point five can be written as two point five zero before combining it with hundredths.
Review and adapt
Estimate the result first and compare the final answer with that estimate. A result off by a factor of ten often signals a place-value error. The key keeps two decimal places for consistent display, although an equivalent value with fewer trailing zeros is also correct. No currency or measurement context is assumed.
