Answer»

You need to CONSIDER the ORDER of operations.

First, we evaluate what is inside the parenthesis:

15−(−3)2+(4−4)3⋅[5+(−3)⋅(−6)]=15−(−3)2+03⋅[5+(−3)⋅(−6)]
15
−

3
⋅
[
5

⋅
(

]
=
15

2
+
0
3
⋅
[
5
+
(
−
3
)
⋅
(
−
6
)
]

Next, we evaluate the exponents:

15−(−3)2+03⋅[5+(−3)⋅(−6)]=15−9+03⋅[5+(−3)⋅(−6)]
15
−
(
−
3
)
2

3

[

⋅
(

]
=

−
9
+
0
3
⋅
[
5
+
(
−
3
)
⋅
(
−
6
)
]

Next, we evaluate any multiplication and division:

15−9+03⋅[5+(−3)⋅(−6)]=15−9+0⋅[5+(−3)⋅(−6)]
15
−
9
+
0
3
⋅
[
5
+
(
−
3
)
⋅
(
−
6
)
]
=
15
−
9
+
0
⋅
[
5
+
(
−
3
)
⋅
(
−
6
)
]

15−9+0⋅[5+(−3)⋅(−6)]=15−9+0
15
−
9
+
0
⋅
[
5
+
(
−
3
)
⋅
(
−
6
)
]
=
15
−
9
+
0

Finally, we evaluate any ADDITION and subtraction:

15−9+0=6
