Integer Part ab/c Numerator ab/c Denominator

Once calculation is done after pressing  =  button, answer from fraction format could be get by pressing ab/c again

2.8 Enter Angle With Degree Minute Second Format

Angle from DMS format can be entered with ° ′ ″ Button

Calculated answer can be converted to DMS format by pressing ° ′ ″ button again.

2.9 Change Answer format.

Answer could be formated in three ways.

1. Fix - (Fixed number of decimal points)

2. Sci - (Answer will be shown as a value into a a power of ten)

3. Norm (Answer will shown as normal. If the space is not enough to show the full value answer might be shown from Sci format)

Long Press 0.00 Key or Press SHIFT + (*) and get the menu and select the format. Number of decimal points could be changed with the arrow button availabe in the selections.

2.10 Working with percentage calculations

Enter 2 5 0 x 1 2%

2. How to calculate the price after 12% of tax is added to 250 ?

Enter 2 5 0 + 1 2%

3. How to calculate the price after 12% of discount is added to 250 ?

Enter 2 5 0 - 1 2%

4. What is the percentage value of 5/6 ?

Enter 5÷6%

2.11 Getting log for any base

To get log value of x in base n (Replace n and x with required values)

Enter Log(n,x)

 

3.0 Graph Mode

3.1 Drawing Graphs

Press Mode and select the Graphs Mode.

Enter the function. For example type Cos X and press  =  button. Then new window will open and it will show the graph.

Multiple functions can be entered with  : 

For example if Cos X and Sin X need to be drawn together, enter the expression Cos X : Sin X and press  = 

 

3.2 Sharing Graphs

Press the share button available in the graph window and select the destination which need to be shared.

 

4.0 Linear Equation Mode

4.1 Solving Linear Equations

Press Mode and select the Linear Equation Mode. Linear equations can be solved only if sufficient number of equations are given.

To solve following equation

X + Y = 3

X - Y = 5

Enter the expression X+Y=3:X-Y=5 and press  =  button. Then answer will be shown as X = 4. Press again  =  . Then answer shown as Y = -1.

Make sure each linear equation is separated with  :  button and use special  =  button for enter = in the expression which can be found in the middle right corner of the calculator.
