va rog sa ma ajutati urgent! multumesc.

Answer 1

1. =300-(108+46×2):10-10-10
=300-(108+92):10-10-10
=300-200:10-10-10
=300-20-10-10
=280-10-10
=270-10
=260

2. =5×(1033+437):6+9-(12+3)
=5×1470:6+9-(12+3)
=5×1470:6+9-15
=7350:6+9-15
= 1225+9-15
= 1234-15
=1219

3. =[(324-32)×2-(200-86)]:10
=(292×2-214):10
=(584-214):10
=370:10
=37

4. (1-1)×[69-(345:5)]+5
=0×(69-69)+5
=0×1+5
=0+5
=5

5. [(315+138):3]+45+104
=(453:3)+45+104
=151+45+104
=196+104
=300
