Grade 3 Math

Subtract hundreds and tens

On this page children practise subtracting three-digit numbers that contain only hundreds and tens — building confidence before full three-digit subtraction. Start with the short method and the examples, then use the online practice or print a worksheet with answers.

How to solve this

  • Subtract hundreds from hundreds and tens from tens; borrow from the hundreds if tens are not enough.
  • To borrow: reduce the hundreds digit by 1 and add 100 (10 tens) to the tens column.
  • Check by adding: result + subtracted number must equal the starting number.

Examples

580 − 240 = ?

340

760 − 320 = ?

440
