4-digit by 3-digit Multiplication with Grid Support Including ... - Free Printable

Let’s solve each multiplication problem step by step. We’ll multiply the 4-digit number by the 3-digit number using standard multiplication (you can think of it as breaking the bottom number into hundreds, tens, and ones, multiplying separately, then adding).

We’ll do all 9 problems one by one.

Problem 1: 9232 × 536

Break 536 into 500 + 30 + 6

→ 9232 × 6 = 55,392
→ 9232 × 30 = 276,960
→ 9232 × 500 = 4,616,000

Add them:

55,392
