Add and multiply decimals

Line up the dots, so tenths sit over tenths and hundredths over hundredths. Then add or take away like whole numbers: 2.71 + 1.25 = 3.96.

Worked example

9.08 − 3.52

Answer: 5.56

Write both to hundredths and keep the dots in a column: 9.08 − 3.52. That’s 908 − 352 hundredths = 556 hundredths, which is 5.56.
