If a = -37 mod 7 and b = 37 mod 7, what is the value of a + b?Select one:a.4b.7c.None of the othersd.0e.2

First, let's find the values of a and b.

a = -37 mod 7 means that a is the remainder when -37 is divided by 7. When you divide -37 by 7, the remainder is -2. So, a = -2.

b = 37 mod 7 means that b is the remainder when 37 is divided by 7. When you divide 37 by 7, the remainder is 2. So, b = 2.

Now, let's add a and b together.

a + b = -2 + 2 = 0

So, the value of a + b is 0. Therefore, the answer is d. 0.
