Substitute the symbols into the equation first, then apply BODMAS (Brackets, Orders, Division, Multiplication, Addition, Subtraction) carefully.
Substitute the symbols into the equation first, then apply BODMAS (Brackets, Orders, Division, Multiplication, Addition, Subtraction) carefully.
Step 1: Write down the substitution rules
Given replacements: I means +, J means x, K means /, and L means -.
Step 2: Substitute symbols into the given expression
Given expression: (24 J 3) K 6 I (14 J 2) L 19 =? After substituting: (24 * 3) / 6 + (14 * 2) - 19.
Step 3: Solve using BODMAS rule
First solve brackets: (72) / 6 + (28) - 19. Next perform division: 72 / 6 = 12. Expression becomes 12 + 28 - 19.
Step 4: Perform final addition and subtraction
Add: 12 + 28 = 40. Subtract: 40 - 19 = 21.
A: 19 is incorrect because it misses the final subtraction step. C: 34 is incorrect due to order of operations error. D: 15 is incorrect due to incorrect calculation.
B is correct because replacing symbols and applying BODMAS gives 21.
Always evaluate expressions inside parentheses first before applying division and multiplication from left to right.
