Question

Zad 4 i 6 :) Trzeba rozpisać np 9-6:(-2)+2=9+3+2=12
Proszę pomóżcie :/

Answer 1

Zadanie 4 ; a) = 5 * 3 = 15 ; b) = 8 - 3 * (-3) = 8 + 9 = 17; c) = 5 * (-1) + 12 = -5 + 12 = 7 ; d) = 2 + 4 * (-3) - (-6) = 2 -12 + 6 = -10+6 = -4 ; e) = 4 - 2 * 3 + 3 = 4 - 6 + 3 = -2 + 3 = 1 ; f) = 3 + 4 * 4 +8 = 3 + 16 + 8 = 19 + 8 = 27 ; g) 2 * 4 : 2 = 8 : 2 = 4 ; h) 6 * 20 : (-3) = 120 : (-3) = -40

Zadanie 6;  a) (-8) * (-3) = 24 to wstawiamy znak > ; b) 9 * (-1) = -9 i wstawiamy znak <; c) -16 * 7 = -112 i wstawiamy znak <; d) 4>0 ; e) -2 < 0 ; f ) -36 : (-2) = 18 > 0

Answer 2

zad 4

a) = 5 * 3 = 15

b) = 8 - 3 * (-3) = 8 + 9 = 17

c) = 5 * (-1) + 12 = -5 + 12 = 7

d) = 2 + 4 * (-3) - (-6) = 2 -12 + 6 = -10+6 = -4

e) = 4 - 2 * 3 + 3 = 4 - 6 + 3 = -2 + 3 = 1

f) = 3 + 4 * 4 +8 = 3 + 16 + 8 = 19 + 8 = 27

g) 2 * 4 : 2 = 8 : 2 = 4

h) 6 * 20 : (-3) = 120 : (-3) = -40

zad 6

a) (-8) * (-3) = 24 więc wstawiamy znak >

b) 9 * (-1) = -9 więc wstawiamy znak <

c) -16 * 7 = -112 wstawiamy znak <

d) 4>0

e) -2 < 0

f) -36 : (-2) = 18 > 0
