Answer 1

(xy) + 10wz

 

First we substitute values.

 

(5*10) + 10(-1)(4)

 

Using PEMDAS, we handle the terms in parentheses.

 

50+10(-1)(4)

 

Next is multiplication and division from left to right.  There is only multiplication.

 

50 + (-40)

 

Next is add or subtract from left to right.  There is only addition.

 

Your solution is 10
