1. refer to expression 1 and expression 2. expression 1 6 ⋅ 7- 3/2⋅9+4/3 expression 2 5+4⋅2+6-2⋅2-1 (a) what is the value of expression 1? (b) insert parentheses in expression 2 so that it has a value of 19. then show why your expression has a value of 19.

The vaule of expression 1 is 

25

with expression 2  5+4*2+6-2*2-1

just put parethhesis around the 5 and 4 so it looks like this (5+4)*2+6-2*2-1

it has this vaule now because you add 5+4 first now which changes the pemdas ordor around because before additon was the last thing but with parethisis it is the first

im using the * for multiplication

32.10 is the correct answer
