Answer 1

Răspuns:

a) 30-(18-12)=30-6=24

(30-18)-12=12-12=0

24 > 0

b) (50-20)+10=30+10=40

50-(20+10)=50-30=20

40 > 20

c) 24-(8:4)=24-2=22

(24-8):4=16:4=4

22 > 4

d) (32+32):8=64:8=8

32+(32:8)=32+4=36

8 < 36

Answer 2

Explicație pas cu pas:

a)

$30 -(18-12)=30-6=24$

$(30-18)-12=12-12=0$

$\red{24 \: > \: 0}$

b)

$(50-20)+10=30+10=40$

$50-(20+10)=50-30=20$

$\red{40 > 20}$

c)

$24-(8:4)=24-2=22$

$(24-8):4=16:4=4$

$\red{22 > 4}$

d)

$(32+32):8=64:8=8$

$32+(32:8)=32+4=36$

$\red{8 < 36}$
