Answer 3

Start with u + v + w

then replace u with -10 to get -10 + v + w

replace v with 4 to get -10 + 4 + w

and finally replace w with 8 to get -10 + 4 + 8

We can do these replacements/substitutions because we are given u = –10, v = 4, and w = 8

Answer 4

Once all of the variables are gone and replaced with numbers, you follow PEMDAS to evaluate the math expression

Answer 5

yes the answer is 2 .
