🔍 Explanation:
Each problem involves
subtracting two 3-digit numbers. Some require
borrowing (regrouping), especially when the digit in the minuend is smaller than the corresponding digit in the subtrahend.
For example:
- $ 662 - 452 $:
$ 662 - 452 = (600 - 400) + (60 - 50) + (2 - 2) = 200 + 10 + 0 = 210 $
- $ 519 - 290 $:
$ 519 - 290 = 519 - 200 - 90 = 319 - 90 = 229 $
- $ 359 - 310 $:
$ 359 - 310 = 49 $ — simple subtraction
- $ 923 - 613 $:
$ 923 - 613 = 310 $
All calculations follow standard subtraction rules with borrowing where necessary.
