F = 1.8C + 32
C = -30
Plug -30 in for C in the formula:
F = 1.8(-30) + 32
First you must multiply 1.8 and -30 per the rules of PEMDAS
F = -54 + 32
Next you will add -54 and 32
When adding a positive number with a negative number you will act as if you are subtracting the two numbers, then take the sign of the largest number (disregarding the signs). In this case the largest number is 54 and its sign is negative. Your answer will have a negative sign.
F = -22
Hope this helped!
