Basic Functions
The addition (sum function) is used by clicking on the "+" button or using the keyboard. The function results in a+b. Subtraction
The subtraction (minus function) is used by clicking on the "-" button or using the keyboard. The function results in a-b. Multiplication
The multiplication (times function) is used by clicking on the "x" button or using the keyboard "*" key. The function results in a*b. Division
The division (divide function) is used by clicking on the "/" button or using the keyboard "/" key. The function results in a/b. Sign
The sign key (negative key) is used by clicking on the "(-)" button. The function results in -1*x. Square
The square function is used by clicking on the "x^2" button or type "^2". The function results in x*x. Square Root
The square root function is used by clicking on the "x" button or type "sqrt()". This function represents x^.5 where the result squared is equal to x. Raise to the Power
The raise to the power (y raised to the x function) is used by clicking on the "y^x" button or type "^". Natural Exponential
The natural exponential (e raised to the x) is used by clicking on the "e^x" button or type "exp()". The result is e (2.71828...) raised to x. Logarithm
The logarithm (LOG) is used by clicking on the "LOG" button or type "LOG()". Natural Logarithm
The Natural logarithm (LN) is used by clicking on the "LN" button or type "LN()". Inverse
Multiplicative inverse (reciprocal function) is used by pressing the "1/x" button or typing "inv()". This function is the same as x^-1 or dividing 1 by the number. Exponent
Numbers with exponents of 10 are displayed with an "e", for example 4.5e+100 or 4.5e-100. This function represents 10^x. Numbers are automatically displayed in the format when the number is too large or too small for the display. To enter a number in this format use the exponent key "EEX". To do this enter the mantissa (the non exponent part) then press "EEX"...
