This Calculator can perform following operations:

1. Plus(+),Minus(-), Multiplication(*) and division(/).
2. Power (squire root, inverse, square, cube,X^Y).
3. Trigonometry function(sin,cos,tan).
4. Memory function(RCL,MR)

You can store ANS by simply giving a number and pressing equal to (=) button.

Normal calculation:

Our calculator perform addition, subtraction, multiplication and division between two numbers. You can use previous answer/result as one of two numbers.

For example

1. 12+34 = 46
2. 12.345+34 = 46.345
3. 12+34.345 = 46.345
4. 12.345+94.8523 = 107.1973

Also can do subtraction, multiplication and division.

Also can use previous answer as one number of this operation.

For example:

If previous answer is 46 then

1. ANS + 34 = 80
2. ANS + 34.456 = 80.345
3. ANS + ANS = 92

Also can do subtraction, multiplication and division using answer as a number.

If you do not give a number by default it will give u ANS as the number.

When you press one button, pressing will do some action if this button pressing is applicable for this stage.

For example:

If small display containing 12.563 then POINT (.) button will be disable. If you press ANS then you cannot press any number or point at this stage until pressing an operator.

This calculator can display 12-digit number. So if your answer exits 12 digits then it shows a math error. After math error happens previous result will be intact in the answer (ANS).

Power function:

You can do power function like square, root, cube, power.

For example:

1. 169^1/2 = 13(root)
2. 16^-1 = 0.0625
3. 12^2 = 144 (square)
4. 6.6^2 = 43.56
5. 5^3 = 125 (cube)
6. 5.5^3 = 166.375
7. 2^10 = 1024
8. 2.2^10 = 2655.992919
9. 12^1.3 = 25.28922843

You an n use previous result/answer as operand.

For doing this simply press the operator button or press ANS and then press operator.

If ANS = 8

1. ANS^1/2 = 2.828427076
2. ANS^-1 = 0.125
3. ANS^2 = 64
4. ANS^3 = 512
5. ANS^2.2 = 97.00586700
6. ANS^6 = 262144
7. ANS^ANS = 16777216

Trigonometry function:

Can do sin, cos, tan functions. Inverse trigonometry function will be in next version.

** Here it is important that angle if these trigonometry functions will be in degree.

For example:

1. Sin70 = 0.939692620
2. Cos70 = 0.342020143
3. Tan70= 2.747477419

Also use previous ANS for the number

If ANS = 40.6

1. SinANS = 0.650774217
2. CosANS = 0.759271307
3. TanANS = 0.857103661

Can calculate –ve angel in degree for example sin-30 = -0.5

Memory function:

Has a memory M that is common in every calculator. Can do memory recall by pressing MR button.

Use M+, M- for adding, subtracting some value in memory. For adding or subtracting just give a number and press M+ or M-.

Can also M+, M- current answer

Our calculator can store 12 number as memory those are A, B, C, D, E, F, G, H, I, J, J, K, L by pressing RCL button.

FOR inserting/ storing memory go to the memory by pressing RCL, and then insert a value or number and press store button for storing data into the corresponding memory.

Just you will find a real-life use. Do you often borrow money from someone else but forget to return? Or you’ve lent somebody and want to remind him about returning? Then “Self Banking” will be the exact choice.  It also has a personal savings feature, which will help you to save.
