Zorluk: OrtaSimplification and BODMAS Rule
Evaluate the following mathematical expression using the standard BODMAS rule:
40% of 150+[72÷{18(212×4+115)}]40\% \text{ of } 150 + \left[ 72 \div \left\{ 18 - \left( 2\frac{1}{2} \times 4 + \overline{11 - 5} \right) \right\} \right]
What is the final simplified numerical value?

Cevap: 96

Cevap

The simplified numerical value of the given expression is 96.
Applying the standard BODMAS rule: first evaluate the vinculum 115=6\overline{11 - 5} = 6. Next, evaluate inside the round brackets: 2.5×4+6=162.5 \times 4 + 6 = 16. Then simplify inside the curly braces: 1816=218 - 16 = 2. Following that, perform division inside the square brackets: 72÷2=3672 \div 2 = 36. Separately, evaluate the percentage term: 40% of 150=6040\% \text{ of } 150 = 60. Summing these two terms gives 60+36=9660 + 36 = 96.

Adım Adım Çözüm

1
Evaluate the bar (vinculum) expression.
\overline{11 - 5} = 6
The vinculum (bar) has highest priority within bracket operations.
2
Simplify the terms within the round parentheses.
2\frac{1}{2} \times 4 + 6 = 10 + 6 = 16
Perform multiplication before addition inside parentheses.
3
Evaluate the expression inside the curly braces.
18 - 16 = 2
Subtract the result of the round brackets from 18.
4
Perform the division inside the square brackets.
72÷2=3672 \div 2 = 36
Divide 72 by the value obtained from curly braces.
5
Calculate the percentage component of the expression.
40\% \text{ of } 150 = \frac{40}{100} \times 150 = 60
The word 'of' indicates multiplication applied to the percentage value.
6
Perform the final addition.
60 + 36 = 96
Add the result of the percentage calculation to the result of the bracket evaluation.
