Question:

Simplify: [tex]30 - [11 - (3 - 15)][/tex].

Provide your answer below:


Sagot :

To simplify the expression [tex]\(30 - [11 - (3 - 15)]\)[/tex], we need to evaluate it step by step, starting from the innermost parentheses and working our way outward.

1. Evaluate the innermost expression:
[tex]\[ 3 - 15 \][/tex]
Subtracting 15 from 3 gives:
[tex]\[ 3 - 15 = -12 \][/tex]

2. Replace the innermost expression with its result:
Now the expression becomes:
[tex]\[ 30 - [11 - (-12)] \][/tex]

3. Evaluate the next expression inside the brackets:
[tex]\[ 11 - (-12) \][/tex]
Subtracting [tex]\(-12\)[/tex] is the same as adding 12:
[tex]\[ 11 - (-12) = 11 + 12 = 23 \][/tex]

4. Replace the inner expression with its result:
Now the expression is:
[tex]\[ 30 - 23 \][/tex]

5. Finally, evaluate the outer expression:
[tex]\[ 30 - 23 = 7 \][/tex]

Thus, the simplified result of the expression [tex]\(30 - [11 - (3 - 15)]\)[/tex] is:
[tex]\[ \boxed{7} \][/tex]
