Evaluate the expression when a =7​, b=2​, c -4and d=-2.

Answer 1

The given values are:

a = 7
b = 2
c = -4
d = -2

Let's evaluate the expression based on these values:

a + b * c - d

Substituting the given values:

7 + 2 * (-4) - (-2)

Simplify the multiplication first:

7 + (-8) - (-2)

Now simplify the subtraction:

7 - 8 + 2

Finally, subtract:

-1 + 2

The final value of the expression is 1.
