Answer :
If you would like to evaluate f - 2 * g for f = 3 and g = 27, you can do this using the following step:
f - 2 * g = 3 - 2 * 27 = - 51
The correct result would be - 51.
If you would like to evaluate x * 0 + y * 0 for x = 3 and y = 2, you can do this using the following step:
x * 0 + y * 0 = 3 * 0 + 2 * 0 = 0 + 0 = 0
The correct result would be 0.
f - 2 * g = 3 - 2 * 27 = - 51
The correct result would be - 51.
If you would like to evaluate x * 0 + y * 0 for x = 3 and y = 2, you can do this using the following step:
x * 0 + y * 0 = 3 * 0 + 2 * 0 = 0 + 0 = 0
The correct result would be 0.
