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"...
