-25 + 43 = 18
7.2 to 10 = 72 to 100 = 18 to 25
18 + 3 = 21
9x + 9 - 1 = 9x + 8
18 + 10 + 20 + 30 + 15 + 50= 143
There is no need to simplify this, it is only a sum. 21 + (10/2) - 18 = 8

-25 + 43 = 18
6+6+6+(81-91)+1000; First add together the sixes 18+(81-91)+1000; Next we add the terms in parenthasis 18+(-10)+1000; Since we have a negative 10, we chang the sign to minus 18-10+1000; Now we subtract 18-10 8+1000; Finally, 1000+8 = 1008 1008
It is: 34 -5y simplified
18 to 25
18 + 10 + 28 + 10 = 66
18 + 2 + 10 = 30
7.2 to 10 = 72 to 100 = 18 to 25
18 + 10 = 28
-45 + 18 = -27
