Step-by-step explanation:
7 - r/8 - 3d
what do we need to do ?
just calculate the value of the expression by using the given values for the variables ?
what's the problem ? this is just basic calculation.
7 - 32/8 - 3×2 = 7 - 4 - 6 = -3
remember (please, for your life !) that multiplication and division always happens before any addition or subtraction (except for the case, where brackets force us in a different direction).
