Apply BODMAS rule systematically (Division, Multiplication, Addition, Subtraction) after replacing the symbols; always divide first to reduce the numbers.
Apply BODMAS rule systematically (Division, Multiplication, Addition, Subtraction) after replacing the symbols; always divide first to reduce the numbers.
Symbol Replacement
Replace the given symbols with mathematical operators: * becomes -, % becomes +, becomesтИЧ,and@becomes/.Theexpression48 2 * 6% 10 @ 5 becomes 48 * 2 - 6 + 10 / 5.
BODMAS Application
First, perform division (10 / 5 = 2). The expression is now 48 * 2 - 6 + 2. Next, perform multiplication (48 * 2 = 96). The expression is now 96 - 6 + 2.
Final Arithmetic
Solve addition and subtraction from left to right: 96 - 6 = 90, and 90 + 2 = 92.
A: Results from incorrectly performing addition before multiplication (e.g., 48*(2-6+2) = -96). C: Results from ignoring BODMAS and calculating strictly left-to-right (48*2=96, 96-6=90, 90+10=100, 100/5=20... error). D: Results from misapplying the sequence of operations or arithmetic errors.
B is correct because replacing the symbols and applying BODMAS (48 * 2 - 6 + (10 / 5) = 96 - 6 + 2) yields exactly 92.
Always ensure you perform division and multiplication before addition and subtraction; common errors occur when students ignore the priority of division over addition.
