Let’s solve each multiplication problem step by step. We’ll multiply the two-digit numbers using the standard method — breaking it into parts and adding them up.

Problem 1: 52 × 84
Step 1: Multiply 52 by 4 (the ones digit of 84)
→ 52 × 4 = 208
Step 2: Multiply 52 by 80 (the tens digit of 84 is 8, so we’re really doing 52 × 80)
→ 52 × 8 = 416 → then add a zero → 4160
Step 3: Add the two results
→ 208 + 4160 =
4368
✔ Final Answer for #1:
4368

Problem 2: 67 × 63
Step 1: Multiply 67 by 3
→ 67 × 3 = 201
Step 2: Multiply 67 by 60
→ 67 × 6 = 402 → add a zero → 4020
Step 3: Add
→ 201 + 4020 =
4221
✔ Final Answer for #2:
4221

Problem 3: 53 × 68
Step 1: 53 × 8 = 424
Step 2: 53 × 60 = 53 × 6 = 318 → add zero → 3180
Step 3: 424 + 3180 =
3604
✔ Final Answer for #3:
3604

Problem 4: 43 × 50
This one is easier because multiplying by 50 is like multiplying by 5 and adding a zero.
Step 1: 43 × 5 = 215
Step 2: Add a zero →
2150
(You can also think: 43 × 50 = 43 × 5 × 10 = 215 × 10 = 2150)
✔ Final Answer for #4:
2150

Problem 5: 91 × 57
Step 1: 91 × 7 = 637
Step 2: 91 × 50 = 91 × 5 = 455 → add zero → 4550
Step 3: 637 + 4550 =
5187
✔ Final Answer for #5:
5187

Problem 6: 37 × 49
Step 1: 37 × 9 = 333
Step 2: 37 × 40 = 37 × 4 = 148 → add zero → 1480
Step 3: 333 + 1480 =
1813
✔ Final Answer for #6:
1813
