Modes

Standard Mode:

• Calculations follow the standard mathematical operator precedence rules (PEMDAS).
• Example: 3 + 5 * 2 = 13 (multiplication is performed first).

Left to Right Mode:

• Calculations are performed from left to right without considering operator precedence.
• Example: 3 + 5 * 2 = 16 (calculations are done left to right).

Scientific Mode:

Sin and Cos:

• Calculates the values of sine and cosine. The input must be in degrees. The calculator will automatically convert the value to radians for the calculation.

Logarithms:

• Two types of logarithms are available:
  • Natural Logarithm (LN): Logarithm with the natural base (e).
  • Base 10 Logarithm: Logarithm with base 10.
• Negative numbers are not supported as logarithms are only defined for positive numbers.

Square Root:

• Calculates the square root of a number. Negative numbers are not supported as the square root is only defined for non-negative numbers.

Result Format:

• High Precision: Displays the result with full detail.
• Rounded (2 Decimal Places): Displays the result in a simpler format. Use the down and up arrows to find out.

Conversion Mode:

• There are several conversions: length, mass, and others. Please explore.

• When you open the calculator, by default it will use the standard calculation method.
• The letter X is allowed for multiplication, and the symbol : is allowed for division.
• Invalid inputs will be removed from the input field.
