In problems #1 and #2, Insert grouping symbols so that the numerical expression has the values given in parts (a), (b), (c).

#1: -3 * 4 - 5

(a) 3 "I think the answer to (a) is -3 (4 -5 )which would =3 "

(b) -17 "I think the answer to (b) is (-3.4) -5 which would = -17 "

(c)-7

Problem #2: 7 - 5^2 +1

(a) 5

(b) -19

(c) -17 "I think the answer to (c) is ( 7 - 5^2 ) + 1= -17 "
