Question

consider the expression 5/2 = (-9)
q9 part a
write the expression as an equivalent addition expression.
q10 part b
evaluate the expression.

Explanation:

Step1: Rewrite as addition

The subtraction $a - b$ can be rewritten as $a+(-b)$. So, $5 - 7$ can be written as $5+(-7)$.

Step2: Evaluate the sum

We know that when adding a positive and a negative number, we subtract the absolute - values and take the sign of the number with the larger absolute value. $|5| = 5$ and $|-7| = 7$. Since $7>5$, the result is negative. $5+(-7)=-(7 - 5)=-2$.

Answer:

Part A: $5+(-7)$
Part B: $-2$
