Rounding Off
If digit<5, round down; if≥5, round up\text{If digit} < 5 \text{, round down; if} \geq 5 \text{, round up}
Commutative (Addition)
a+b=b+aa + b = b + a
Commutative (Multiplication)
a×b=b×aa \times b = b \times a
Associative (Addition)
(a+b)+c=a+(b+c)(a + b) + c = a + (b + c)
Associative (Multiplication)
(a×b)×c=a×(b×c)(a \times b) \times c = a \times (b \times c)
Distributive Property
a×(b+c)=a×b+a×ca \times (b + c) = a \times b + a \times c
Additive Identity
a+0=aa + 0 = a
Multiplicative Identity
a×1=aa \times 1 = a
Multiplicative by Zero
a×0=0a \times 0 = 0
Addition of Integers (same sign)
Add absolute values, keep the sign\text{Add absolute values, keep the sign}
Addition of Integers (different sign)
Subtract smaller from larger, take sign of larger\text{Subtract smaller from larger, take sign of larger}
Subtraction Rule
a−b=a+(−b)a - b = a + (-b)
Absolute Value
∣a∣=a if a≥0,∣a∣=−a if a<0|a| = a \text{ if } a \geq 0, \quad |a| = -a \text{ if } a < 0
Fraction
ab,b≠0\dfrac{a}{b}, \quad b \neq 0
Equivalent Fractions
ab=a×kb×k\dfrac{a}{b} = \dfrac{a \times k}{b \times k}
Addition (same denominator)
ac+bc=a+bc\dfrac{a}{c} + \dfrac{b}{c} = \dfrac{a + b}{c}
Addition (different denominator)
ab+cd=ad+bcbd\dfrac{a}{b} + \dfrac{c}{d} = \dfrac{ad + bc}{bd}
Subtraction
ab−cd=ad−bcbd\dfrac{a}{b} - \dfrac{c}{d} = \dfrac{ad - bc}{bd}
Mixed to Improper
abc=ac+bca\dfrac{b}{c} = \dfrac{ac + b}{c}
Decimal to Fraction
0.ab=ab1000.ab = \dfrac{ab}{100}
Fraction to Decimal
ab=a÷b\dfrac{a}{b} = a \div b
