Mathematical Notation & Formulas

• { } indicates a set.
• ∈ indicates an element belongs to a set
• + indicates an addition operation
• - indicates a subtraction operation
• = / ≠ indicates equality/inequality.
• ∀ / ∃ indicates "for all" / "there exists"
• → / ≤ / ≥ indicates "implies"/ "less than or equal to" / "greater than or equal to"
• ℝ indicates set of Real numbers
• ∞ indicates infinity
• -∞ indicates negative infinity
• { x | ... } indicates the set of all elements x such that ... .
• A function f(x) can be written as f : ℝ → ℝ, meaning f maps real numbers to real numbers.
• For all a ≠ 0 and b ≠ 0:
• a + a = 2a
• a + 0 = a
• a - a = 0
• a * 1 = a
• a / a = 1
• a / b = a/b
• a + (b + c) = (a + b) + c
• a * (b * c) = (a * b) * c
• a + b = b + a
• a * b = b * a
• a - b = a + (-b)
• a / b = a *(1/b)
• If a > b and c > 0 then ac > bc
• If a > b and c < 0 then ac < bc
• If a > b and b > c, then a > c
• |a| is the absolute value of a, which is always positive.
• x > 0 indicates x is positive.
• x < 0 indicates x is negative.
• x = 0 indicates x is zero.
• a ≡ b (mod c) means a - b is divisible by c.
• a^b means a raised to the power of b.
