5 – 3 x 2 + 4 – 4 : 2
5 – 6 + 4 – 2
5 – 6 + 4 – 2 = 1
2.-
( 4 + 3 ) – ( 3 x 2 ) + 1
4 + 3 = 7
3 x 2 = 6
7 – 6 + 1
7 – 6 + 1 = 2
3.-
3 x ( 4 x 2 – 3 ) – ( 4 + 6 : 3 )
3 x ( 4 x 2 – 3 ) – ( 4 + 6 : 3 )
3 x ( 8 – 3 ) – ( 4 + 2 )
3 x 5 – 6
15 – 6 = 9
4.-
[ 15 – ( 2 – 10 : 2) ] x [ 5 + ( 3 x 2 – 4)] – 3 + ( 8 – 2 x 3 ) =
[ 15 – 3 ] x [ 5 + 2 ] – 3 + 2 =
( 15 – 3 ) x ( 5 + 2 ) – 3 + 2 =
12 x 7 – 3 + 2 =
84 – 3 + 2 = 83

9.-
45 : (-5) - 6 (-4) - (-5)(-3)=
(-9) - (-24) - (+15)=
(-9) + (+24) + (-15)=
(-24) + (+24)=0
10.-
3 • 2 − 5 + 4 • 3 − 8 + 5 • 2 =
6 − 5 + 12 − 8 + 10 =
6 − 5 + 12 − 8 + 10 = 15
