12 - (3^2 - 7) * 4 = 12 - (9 - 7) * 4 = 12 - 2 * 4 = 12 - 8 = 4
88. 12*7=84+4=88
It is: 252
7 20/4: = 7 + 20/4 = 7 + 5 = 12 (this is a whole number)
The smallest number that both 7 and 12 can go into is their least common multiple (LCM). To find the LCM, you can multiply the two numbers together and then divide by their greatest common divisor (GCD), which is 1 in this case. Thus, the LCM of 7 and 12 is 84. Therefore, 7 and 12 can both go into 84.
