Scientific Operations Hierarchy
In advanced mathematics, functions (trigonometric, logarithmic, exponential) are treated as group arguments. This means sin(x + y) evaluates x + y first (like a Bracket), then calculates the sine, before resolving other operations.
Scientific Priority Order
1
Function Arguments (Brackets)
Evaluate inside sin(), log(), sqrt() first
2
Function Evaluation & Exponents
Calculate function value and powers (O)
3
Basic Arithmetic
Division/Multiplication, then Addition/Subtraction
Common Pitfalls in Scientific Calculations
Scientific operators carry strict priority rules. These mistakes are common when applying BODMAS:

Trig ArgumentsClick to see
sin 30 + 15 → sin(45) ✗
sin(30) + 15 → 0.5 + 15 = 15.5 ✓
Evaluate functions before addition
Negative ExponentsClick to see
-3² → (-3) × (-3) = 9 ✗
-3² → -(3 × 3) = -9 ✓
Exponents apply before unary negation
