is there a easier way to multiply 92
x95

instead of doing al;l the ;long multiplication?

    I don't know of any easier way.

    Believe me, the practice will help you for a long time. You should know the multiplication tables as well as you know your own name.

    oh...... k thanks anyway

    Brian, glad that you asked.
    All you need to do is to look at the question this way:

    92x95

    92=100-8
    95=100-5

    92*95
    =(100-8-5)||5*8
    =87||40
    =8740

    (The || means stick the numbers together)

    Try another example:

    98*94
    =(100-2-6)||2*6
    =9212

    With a little practice, you do not have to write them down and do the calculation mentally.

    What MathMate did:
    92*95
    (100-8)(100-5)
    10,000 - 500 - 800 + 40
    8740
    or my way
    95 (100 - 8)
    9500 - 760
    8740
