(3.2^2– 4) + 3 – (12 – 5.2) + (5 + 16:2^2) -5+ (10– 2^3)=
=10.24−4+3−(12−5.2)+5+16/22−5+10−23
=6.24+3−(12−5.2)+5+16/22−5+10−23
=9.24−(12−5.2)+5+16/22−5+10−23
=9.24−6.8+5+16/22−5+10−23
=2.44+5+16/22−5+10−23
=2.44+5+16/4−5+10−23
=2.44+5+4−5+10−23
=2.44+9−5+10−23
=11.44−5+10−23
=6.44+10−23
=6.44+10−8
=6.44+2
=8.44
[15 – (2^3 – 10:2)]. [5 + (3.2 – 4)] – 3 + (8 – 2.3)=
=(15−(8−10/2))(5+3.2−4)−3+8−2.3
=(15−(8−5))(5+3.2−4)−3+8−2.3
=(15−3)(5+3.2−4)−3+8−2.3
=12(5+3.2−4)−3+8−2.3
=12(5+−0.8)−3+8−2.3
=(12)(4.2)−3+8−2.3
=50.4−3+8−2.3
=47.4+8−2.3
=47.4+5.7

7 - {5 + 10. [20:5 – 2 + 4.(5 +2.3)] - 8.3^2} + 50.(6.2) =
=7−(5+10(4−2+4(5+2.3))−8.32)+(50)(6.2)
=7−(5+10(2+4(5+2.3)−8.32)+(50(6.2)
=7−(5+10(2+(4)(7.3))−8.32)+(50)(6.2)
=7−(5+10(2+29.2)−8.32)+(50)(6.2)
=7−(5+(10)(31.2)−8.32)+(50)(6.2)
=7−(5+312−8.32)+(50)(6.2)
=7−(317−8.32)+(50)(6.2)
=7−(317−68.89)+(50)(6.2)
=7−248.11+(50)(6.2)
