Subtraction

4644

Step 1: We need to find what number, when subtracted from 9000, gives 4356. This means: 9000 - ? = 4356, so ? = 9000 - 4356. Step 2: Ones: 0 < 6, borrow from tens (also 0), borrow from hundreds (also 0), borrow from thousands. 9 thousands → 8 thousands, 0 hundreds → 10 hundreds → 9 hundreds after borrowing → 0 tens → 10 tens → 9 tens, 0 ones → 10 ones. Step 3: 10 - 6 = 4, 9 - 5 = 4, 9 - 3 = 6, 8 - 4 = 4. Answer: 4644.

₹3610

Step 1: Total money = ₹8500. Money spent on dress = ₹2640, money spent on shoes = ₹2250. Step 2: First find total money spent: 2640 + 2250 = 4890. Step 3: Now subtract: 8500 - 4890. Step 4: 8500 - 4890: 0 < 0, borrow... 8500 - 4890 = 3610. Check: 4890 + 3610 = 8500. Answer: ₹3610.

29857

Step 1: Write 75843 - 45986 (Tth Th H T O). Step 2: Ones: 3 < 6, borrow from tens. 4 tens → 3 tens, 3 ones → 13 ones. 13 - 6 = 7. Step 3: Tens: 3 < 8, borrow from hundreds. 8 hundreds → 7 hundreds, 3 tens → 13 tens. 13 - 8 = 5. Step 4: Hundreds: 7 < 9, borrow from thousands. 5 thousands → 4 thousands, 7 hundreds → 17 hundreds. 17 - 9 = 8. Step 5: Thousands: 4 < 5, borrow from ten-thousands. 7 → 6, 4 → 14. 14 - 5 = 9. Ten-thousands: 6 - 4 = 2. Answer: 29857.

Step 1: Sum of two numbers = 7654. One number = 3928. We need to find the other number. Step 2: Since sum = first number + second number, second number = sum - first number. Step 3: 7654 - 3928. Ones: 4 < 8, borrow. 14 - 8 = 6. Step 4: Tens: 4 < 2? After borrow it is 4, 4 ≥ 2: 4 - 2 = 2... wait: tens digit after borrow is 5-1=4... let me redo: 7654 - 3928. Ones: borrow, 14-8=6. Tens: 5-1=4, 4<2? No, 4≥2, 4-2=2. Hundreds: 6-9, borrow: 16-9=7, thousands: 7-1-3=3... Hmm: 7654-3928: 4-8 borrow→14-8=6; 5-1=4, 4-2=2; 6-9 borrow→16-9=7; 7-1=6, 6-3=3. Answer: 3726.
