EXPONENTS:

Numbers can easily be expressed using exponents.

The symbol for exponent expression is ‘E’
IE: 2.5E+3 = 2500, 2.5E-3 = 0.0025

COMPLEX OPERATORS:

Key: [n-number, r-select, d-divisor, b-base]

With Repetition:
Cwr(n,r) = Combinations
Pwr(n,r) = Permutations

Without Repetition:
Cnr(n,r) = Combinations
Pnr(n,r) = Permutations

Mod(n,d) = Modulus [Mod(6.5, 2) = 0.5]
Log(n,b) = Logarithm [Log(8, 2) = 3]
Abs(n) = Absolute [Abs(-4) = |-4| = 4]
Inv(n) = Inversion [Inv(4) = 0.25]
Fac(n) = Factorial [Fac(4) = 24]

BASIC OPERATORS:

‘^’ = Power Exponent [4 ^ 3 = 64]
‘v’ = Root [2 v 9 = 3] [ 3 v 8 = 2]
‘x’ = Multiplication, ‘/’ = Division
‘+’ = Addition, ‘-‘ = Subtraction

MODES:

‘W’ = Working (shows steps of calculation)
‘D’ = Degrees, ‘R’ = Radians
