Convert symbols immediately and perform division before multiplication to avoid fractional errors in initial steps.
Expression: 4-18×3÷50+33, where - is x, x is ÷, ÷ is +, and + is -.
BODMAS=Brackets,Orders,Division,Multiplication,Addition,Subtraction
Convert symbols immediately and perform division before multiplication to avoid fractional errors in initial steps.
Ignoring the order of operations (BODMAS) and solving the expression from left to right without respecting the precedence of division.
Substitute the Operators
Replace the given signs based on the problem statement: - becomes x, x becomes ÷, ÷ becomes +, and + becomes -.
4×18÷3+50−33
Apply Division
First, perform the division part 18÷3=6.
4×6+50−33
Apply Multiplication
Next, perform the multiplication part 4×6=24.
24+50−33
Perform Addition and Subtraction
Solve the remaining addition 24+50=74, then subtract 74−33.
74−33=41
C is correct because applying the BODMAS rule to the transformed expression 4×18÷3+50−33 yields 41.
This logic is foundational for 'Coding-Decoding' and 'Mathematical Operations' reasoning sections, where accuracy in symbol replacement is key.
