They are four terms of an expression that can be simplified to: 16+h
The expression: 12+15h-14h+4 can be simplified to 16+h by combining like terms
-5+7--4+12 = 18
5 + 1 + 4 + 12 = 22
4 + 6 + 12 + 175 = 197
4 plus 8 plus 12 plus 16 is equal to 40.
The problem of -5 plus 7 - (-4 plus -12) is equal to 18.
