14:22:27 ** We write this sum as 5 * 10^2 + 3 * 10^1 + 6 * 10^0 + 2 * 10^2 + 7 * 10^1 + 9 * 10^0 ______________________________ 8 * 10^2 + 10* 10^1 + 15* 10^0. Since 10 * 10^1 = 10^2 we can write this as 9 * 10^2 + 0 * 10^1 + 15 * 10^0. Since 15 * 10^0 = 10 * 10^0 + 5 * 10^0 = 10^1 + 5 * 10^0 we rewrite this as 9 * 10^2 + 1 * 10^1 + 5 * 10^0. This result is expressed in our place-value system as 915. **

14:24:28 ** For example if a = 2, b = 5 and c = 7 we have a + (b + c) = 2 + (5 + 7) = 2 + 12 = 14 but (a+b) * (a+c) = (2+5) + (2+7) = 7 + 12 = 19. **
