rite an addition expression to represent
m and explain its meaning. (example 8)

Explanation:

Step1: Analyze signs of numbers

We have a negative number - 15 and a positive number 8. When adding a negative and a positive number, we subtract the smaller absolute - value from the larger absolute - value and take the sign of the number with the larger absolute value.

Step2: Calculate absolute values

$| - 15|=15$ and $|8| = 8$. Since $15>8$, we subtract 8 from 15: $15 - 8=7$.

Step3: Determine the sign

Since the number with the larger absolute value is - 15 (negative), the result is negative. So, $-15 + 8=-7$.

Answer:

$-7$
