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=1008
95=1005
92*95
=(10085)5*8
=8740
=8740
(The  means stick the numbers together)
Try another example:
98*94
=(10026)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
(1008)(1005)
10,000  500  800 + 40
8740
or my way
95 (100  8)
9500  760
8740
