Vă rog ajutati-ma dau coronița ^-^

Answer 1

a) (18+14):(6+2)
=32:8=4
b) 24-8×2=8
c) 6+40-16=6+24=30
d) 6+6-3=9
e) 9-3=6
f) 20-10=10

Answer 2

a) (18+2×7) ÷ (12÷2+8÷4)
= (18+14) ÷ (6+2)
=32 ÷ 8
=4
b) 24-24 ÷3 × ( 72÷9 - 2 × 3) ÷4 × 5
=24-24÷3× ( 8 - 6 ) ÷ 4 × 5
= 24-24÷3× 2 ÷4×5
=24-8×2÷4×5
=24-16÷4×5
=24-4×5
=24-20
=4
c) 36÷6+4×2×5-(20-12÷3)
=6+4×2×5-(20-4)
=6+4×2×5-16
=6+8×5-16
=6+40-16
=46-16
=30
d) 42÷7+(6+6)÷2-24÷ (5+3)
=6+12÷2-24÷8
=6+6-3
=12-3
=9
e) (25+20)÷5-(19+5)÷8
=45÷5-24÷8
=9-3
=6
f) 10+(10÷10+10)-(10×1+10)
=10+(1+10)-(10+10)
=10+11-20
=21-20
=1
