Question

a) (–7)² –9 –(–1) + 4² = *

b) 10 + (–4) . (+3) –15 = *

c) 6² + 9–[ (+20) : (–4) + 1 ] = *

d) {–3 –[ (–5)² –(–2³ + 30 ) ] } –36= *

e) 3 + 2 . [(3²- 2⁰) + ( 5¹ - 2²)] + 1 =

f) (-1)⁸ + 6⁰ - [15 + (-40) : (-2)³ ] =

g)14 – [(-1)³ . (-2)² + (-35) : (+5)] =​

Answer 1

Resposta:

a) 30 - (6-1)

30 - 5

= 5

b) 15 + (-3+7)

15 + 4

= 19

c) -6- (-3+2)

-6-(-1)

-6+1

= -5

d) 18- (-5-2-3)

18- (-10)

18 + 10

= 28

e)4+(3-5)+(-2-6)

4+(-2)+(-8)

4-2-8

=-6

f)20-(-6+8)-(-1+3)

20-(2)-(2)

20-2-2

= 16

g)35+(-3)-(-4+7+2)

35-3-(5)

35-3-5

= 27

h)8+(3-10)-(3+5-20)

8+(-7)-(-12)

8-7+12

= 13
