Step-by-step solution for: MathSphere Free Sample Maths Worksheets
Let’s go through each problem step by step.

Part 1: Adding a single digit (problems 1–20)
These are all about adding a small number (like 2, 4, 5, etc.) to a bigger number — mostly 3-digit numbers. The key is to focus on the last digit and carry over if needed.
1. 527 + 5 = ?
7 + 5 = 12 → write down 2, carry 1 → 520 + 10 + 2 = 532
2. 617 + 4 = ?
7 + 4 = 11 → write down 1, carry 1 → 610 + 10 + 1 = 621
3. 146 + 6 = ?
6 + 6 = 12 → write down 2, carry 1 → 140 + 10 + 2 = 152
4. 162 + 9 = ?
2 + 9 = 11 → write down 1, carry 1 → 160 + 10 + 1 = 171
5. 218 + 5 = ?
8 + 5 = 13 → write down 3, carry 1 → 210 + 10 + 3 = 223
6. 149 + 2 = ?
9 + 2 = 11 → write down 1, carry 1 → 140 + 10 + 1 = 151
7. 383 + 7 = ?
3 + 7 = 10 → write down 0, carry 1 → 380 + 10 + 0 = 390
8. 619 + 8 = ?
9 + 8 = 17 → write down 7, carry 1 → 610 + 10 + 7 = 627
9. 276 + 9 = ?
6 + 9 = 15 → write down 5, carry 1 → 270 + 10 + 5 = 285
10. 151 + 9 = ?
1 + 9 = 10 → write down 0, carry 1 → 150 + 10 + 0 = 160
11. 248 + 4 = ?
8 + 4 = 12 → write down 2, carry 1 → 240 + 10 + 2 = 252
12. 814 + 7 = ?
4 + 7 = 11 → write down 1, carry 1 → 810 + 10 + 1 = 821
13. 735 + 5 = ?
5 + 5 = 10 → write down 0, carry 1 → 730 + 10 + 0 = 740
14. 807 + 8 = ?
7 + 8 = 15 → write down 5, carry 1 → 800 + 10 + 5 = 815
15. 6 + 184 = ?
Same as 184 + 6 → 4 + 6 = 10 → 180 + 10 = 190
16. 5 + 227 = ?
Same as 227 + 5 → 7 + 5 = 12 → 220 + 10 + 2 = 232
17. 9 + 666 = ?
Same as 666 + 9 → 6 + 9 = 15 → 660 + 10 + 5 = 675
18. 8 + 777 = ?
Same as 777 + 8 → 7 + 8 = 15 → 770 + 10 + 5 = 785
19. 3 + 888 = ?
Same as 888 + 3 → 8 + 3 = 11 → 880 + 10 + 1 = 891
20. 4 + 789 = ?
Same as 789 + 4 → 9 + 4 = 13 → 780 + 10 + 3 = 793

Part 2: Work out mentally and explain method (problems 21–25)
We’ll solve each and write a simple explanation like the example.
Example given:
187 + 6 = 193
Explanation: “I added three to make 190 then counted on three more to 193”
So we’ll use similar thinking — break it into easy steps.
21. 178 + 5 = ?
178 + 2 = 180, then +3 more = 183
→ 183
Explain: I added 2 to get to 180, then added 3 more to make 183.
22. 388 + 9 = ?
388 + 2 = 390, then +7 more = 397
→ 397
Explain: I added 2 to reach 390, then added 7 more to get 397.
23. 717 + 6 = ?
717 + 3 = 720, then +3 more = 723
→ 723
Explain: I added 3 to make 720, then added 3 more to make 723.
24. 545 + 8 = ?
545 + 5 = 550, then +3 more = 553
→ 553
Explain: I added 5 to get to 550, then added 3 more to make 553.
25. 808 + 6 = ?
808 + 2 = 810, then +4 more = 814
→ 814
Explain: I added 2 to reach 810, then added 4 more to get 814.
