Question

a) 2•(-10)+10
b) 3•(-11)+22:(-2)
c) 3+(-5) la puterea 2 -(-20):(-4)
d) -4•[-7+(-3 la puterea 2 + 6)•(-2)]

Answer 1

a)2×(-10)+10= -20+10= -10

b) 3×(-11)+22÷(-2)= -33-11= -44

c) 3+(-5)² - (-20)÷(-4) = 3+25 -5 = 28-5= 23

d) -4×[-7+ (-3² +6) × (-2)] = -4×[ -7+ ( -9+6) × (-2)]= -4×[ -7+(-3)×(-2)] = -4× [ -7+6 ] = -4× (-1) = 4
