Question

Prove that 45 - 45 = 45.

Answer 1

Answer:

9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 = 45

1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 = 45

Then, 987654321 - 123456789 = 864197532 => 8 + 6 + 4 + 1 + 9 + 7 + 5 + 3 + 2 = 45.

Answer 2

Answer:

45-45=45,

9+8+7+6+5+4+3+2+1=45,

1+2+3+4+5+6+7+8+9=45,

Then, 987654321-123456789=864197532 = 8+6+4+1+9+7+5+3+2=45.

hope answer will be correct...
