Question

36+60:4*2+34
42+54:3*2-18
(760+100)-(430+230)
(970-340)+(250+120)

Answer 1

36+60:4*2+34 =100

60:4=15

15*2=30

36+30=66

66+34=100

42+54:3*2-18 =60

54:3=18

18*2=36

42+36=78

78-18=60

(760+100)-(430+230) =200

760+100=860

430+230=660

860-660=200

(970-340)+(250+120)=1000

970-340=630

250+120=370

630+370=1000
