Answer 1

25 + 13 x 4

= 25 + (13 x 4)

= 25 + 52

= 77

28 + 70 : 14 x 9

= 28 + ((70 : 14) x 9)

= 28 + (5 x 9)

= 28 + 45

= 73

24 - 21 x 11 : 7

= 24 - ((21 x 11) : 7)

= 24 - (231 : 7)

= 24 - 33

= -9

39 + 162 : 18 x (-8)

= 39 + ((162 : 18) x (-8))

= 39 + (9 x (-8))

= 39 + (-72)

= 39 - 72

= -33

27 x (-11) - 84 : 14

= (27 x (-11)) - (84 : 14)

= -297 - 6

= -303
