Let’s solve each multiplication problem step by step. We’ll multiply the 3-digit number by the 2-digit number using standard multiplication (also called long multiplication). Remember: multiply by the ones digit first, then the tens digit, and add the results.

a. 523 × 12
Step 1: Multiply 523 × 2 = 1046
Step 2: Multiply 523 × 10 = 5230 (because the “1” is in the tens place)
Step 3: Add them: 1046 + 5230 =
6276
✔ Final Answer for a:
6276

e. 503 × 30
This one is easy because we’re multiplying by 30 — just multiply by 3 and add a zero at the end.
503 × 3 = 1509 → add a zero →
15090
✔ Final Answer for e:
15090

g. 256 × 41
Step 1: 256 × 1 = 256
Step 2: 256 × 40 = 10240

10496
✔ Final Answer for g:
10496

h. 500 × 30
Multiply 5 × 3 = 15, then add three zeros (two from 500, one from 30) →
15000
✔ Final Answer for h:
15000
