The Effect of JavaScript Plus Equal - Delft Stack

Last character Divide (/) for division Multiply (*) for multiplication Minus (-) for subtraction Plus (+) for addition Plus/Minus (+/-) (F3) Decimal point (.) Square (x²) Fraction (⅟x) Parentheses for controlling calculation order How to calculate percentages The Percent (F1) key is invaluable for calculating discounts and taxes on items. For instance, if you're shopping and want to determine the tax on a $20 item with a 12% tax rate, enter "12%20" to find that the tax amounts to $2.40. To calculate the total cost, simply use the addition key: "20+12%" yields $22.40. For discounts, like a 20% store-wide reduction, key in "20-20%" to find the reduced price, then add the tax if applicable. For example, "20-20%+12%" results in a final cost of $17.92. How to Calculate the Square of a Number The Square (x²) key multiplies a number by itself. For instance, entering "9²" equals 81, as 9 multiplied by 9 equals 81. How to Calculate the Square Root of a Number The Square Root (F2) key calculates the square root of a number, which, when multiplied by itself, yields the original number. For example, "9√" equals 3, or "3+9√" equals 9. How the Fraction Key Works The Fraction (⅟x) key, also known as the reciprocal key, generates a fraction with "1 over x." For instance, entering "⅟4" results in 0.25, as 1 divided by 4 equals 0.25. How to Use the Plus/Minus (+/-) Key The Plus Minus (+/-) key converts a value from positive to negative or vice.

Need to add that. Key in +12%. So now, we're paying $17.92. --> How to calculate the square of a number Square x² - the square key takes whatever value I key in, and squares it. That is, it will multiply it by itself. If I key in 9, press the square key, and then equals, we'll get 81. That is, 9 multiplied by 9 equals 81. Example, 9² = 81 How to calculate the square root of a number Square Root (F2) - Square roots are the opposite of squares. Squares are numbers getting multiplied by themselves. The square root of a number is the value, which when multiplied by itself, gives the original number. Squares and square roots are vice-versa methods. For example, the square of 2 is 4 and the square root of 4 is 2. Example, 9√ = 3, or 3+9√ = 9 How the fraction (or reciprocal) key works Fraction ⅟x - the fraction key, or 1 over x key. (also called the reciprocal key) If you key in 4, and then press the fraction key you will get a fraction with 1 over 4. 1 divided by 4, equals 0.25. Example, ⅟4 = 0.25 How to use the +/- (plus/minus) key The plus minus +/- key takes the value and converts it from a positive value to a negative value, or a negative to a positive value. How to use parentheses in calculations Parentheses to control order of calculations. Something a little more advanced,
