    What is the easiest way to calculate % on a calculator? (not percentage!)

    For example 304 % 43 = 3

    I calculated this by doing 304 - 43, ANS - 43 until I got to a figure less than 43 but greater than 0.
    I'm sure there is a better way.

    Anyone know?

    304 / 43 = 7.069767442
    7.069767442 - 7=0.069767442
    0.069767442 * 43= 3

    OR

    304 / 43 = 7.069767442
    7*43 = 301
    304 - 301 = 3

    take your pick

    Yeah, a button it what I am looking for as my subtraction method really is easier/quicker.
    I just keep pressing the equals button.

    Try working out what 123456 is modulo 427 by pressing the equals button... it'll take you a while :p: To be honest, using the a \equiv a-\left \lfloor \dfrac{a}{n} \right \rfloor \pmod n method (which is the divide by n, then subtract the integer part, then multiply through by n again) gives you the answer directly without you giving yourself an RSI.
