Let the two numbers be represented by 'a' and 'b'. Then, a + b = 645 And a - b = 151............adding these two eqations together gives :- 2a = 796 : a = 398..........and b = 645 - 398 = 247 (or b = 398 - 151 = 247).
645

Guess and check used to be called trial and error. If you look at 645 and realize that 400 and 245 differ by 155, you know you're only four away. So you try 398 and 247 and there you are.
398 and 247.
247 + 398 = 645398 - 247 = 151Therefore the two numbers which add together to make 645 and have a difference of 151 are 247 and 398.
645 - 151 = 494 494 / 2 = 247 247 + 151 = 398 Which means: 398 + 247 = 645 and 398 - 247 = 151
Sum means adding so the sum is 645 + 10 = 655. Hope it helped!
a + b = 645 a - b = 151 Add: 2a = 796 a= 398, making b = 247
The sum of 483 and 162 is 645.

sum is addition difference is subtraction
The sum of -5 and 20 is 15. The distance between -5 and 20 is 25. The sum of the numbers between -5 and 20 is 180. The sum of the numbers from -5 to 20 is 195.
645
1 + 3 + 5 + 15 + 43 + 129 + 215 + 645 = 1,056
