There are four fundamental operations.
These are addition\[\left( + \right)\], subtraction\[\left( - \right)\], multiplication \[\left( \times \right)\] and division \[\left( \div \right)\]
Whenever two or more of these operations occur simultaneously, we overcome on such complex situation by applying the "BODMAS" rule.
This chapter is on the basis of the "BODMAS" rule.
Let us explain this rule briefly.
B \[\to \] Bracket, O \[\to \] Of, D \[\to \] Division, M \[\to \]Multiplication, A \[\to \] Addition, S \[\to \] Subtraction
We solve an expression first for 'bracket' (if available), then for 'of? (if available).
This process goes upto subtraction.
If 'L stands for \['+',\]M' stands for \['-',\] 'N' stands for \['\times ',\] 'P' stands for' \['\div ',\] then 14 N 10 L 42 P 2 M 8 = ?
Given expression \[=14\times 10+42\div 2-8=153\]
Hence, the answer is (b).
