Răspuns:

a. 3×18=54, 32+15=47,20+30=50,132-72=50, b. 16-4=12,72÷4=16,50+1=51,100÷50=2c. 4+20=24,8×5=40,20-5=15,0÷4=0, d. 40-36=4,45÷15=3, 1+2×14=1+28=29,40-20÷5=40-4=36.

6. x =22+44+11+1=78, y= 22+22×24÷4+2=22+22×6+2=22+132+2=156, a. 156÷78=2, b 156-78=78, 156÷78=2, 78-3=76

7. a. 1212÷606=2, 40+1-40=1, 2+2×(2+2×3)=2+2×8=18, 200-144+124-175=56+124-175=180-175=5, 60-2×(30-9)= 60-2×21=60-42=18 b. 40+8×16=40+92=132, 2375-95=2280, 1604+872-2005= 471, 14×(24-325÷(72-7)=14×(24-325÷65)=14×(24--5)=14×19=266, 1004-4×(8+201)=1004-4×209=1004-836=168

c. (20-10×(211-7×30))÷10-1= (20-10×(211-210))÷10-1=(20-10×1)÷10-1=10÷10-1=0, (576-16×5-143÷11)÷3=(576-80-13)÷3=483÷3=161

15+(50+105×(160-4×40))=15+(50×0)=15
