87
Well, let's imagine numbers as friends playing on a see-saw. When we add 74 and 13 together, it's like lifting one friend higher on the see-saw, making the total 87. Then, when we subtract 13 from 87, it's like bringing that friend back down to the same level as the other, which gives us back our original number of 74. It's all about balancing the numbers, just like friends on a see-saw!
120 minus 87 equals 33.

The two equations 74 + 13 = 87 and 87 - 13 = 74 demonstrate the inverse relationship between addition and subtraction. In the first equation, adding 13 to 74 gives you 87, while in the second equation, subtracting 13 from 87 returns you to 74. This showcases how addition and subtraction are inverse operations, with subtraction "undoing" the action of addition.
