The problem is do you add first, or multiply first. The trick is to compromise: split the middle 2 into "1 + 1"
Now you have 2 + 1 + 1 x 4. One of the 1s gets added with the 2 (=3), the other gets multiplied with the 4 (=4). And now you just have 3 + 4, which equals 7
By using compromise, you can bring civility and reciprocation back to mathematics
