5+[4-2(8-5)]
8-5=3
3x2=6
4-6=-2
5+-2=3
so 3 is the answer.
set it up in proper mathematical form
5+[4-2(8-5)]
=5+[4-2(3)]
=5+[4-6]
=5+[-2]
= 3
To solve the expression 5+[4-2(8-5)] in proper mathematical form, follow the order of operations (also known as PEMDAS or BODMAS):
Step 1: Simplify the expression inside the parentheses.
8-5 = 3
Now, substitute the simplified expression back into the original expression:
5+[4-2(3)]
Step 2: Next, simplify any multiplications or divisions.
2(3) = 6
Again, substitute the simplified expression back into the original expression:
5+[4-6]
Step 3: Move from left to right and perform any additions or subtractions.
4-6 = -2
Substitute the result back into the original expression:
5+[-2]
Step 4: Finally, perform the addition in the expression.
5+(-2) = 3
Therefore, the final answer is 3.
