Sure:
52 * 88 = ?
50 * 80 = 4000
50 * 8 = 400
80 * 2 = 160
8 * 2 = 16
4000 + 400 + 160 + 16 = 4576
52 * 88 = 4576
Another ways to multiply 2 two digit numbers:Example-1 (General method for two digit numbers)57*45 = ?
Write one number below the other as shown.
5 7
4 5
--------
25 6 5
Start from Right column : 7*5 = 35. Write 5. Carry 3.
Now cross multiply and add. That is 5*5+4*7 = 53. Now add the carry. So 53+3 = 56. Write 6. Carry 5.
Now consider left column. 5*4 = 20. Now add the carry. So 20+5 = 25. Write 25.
Thus the result is 2565. You will realize that this method is simple than the explanation while performing calculations.
Example-2 (For two digit numbers that have large values)98*97 = ?
98 2
97 3
----------
95 06
First, write one number below another number. To the right side of each number, write the difference of that number from 100 (That is 100-98=2 and 100-97=3).
Now multiply the right side column. So 2*3=06
And do cross subtraction. That is 98-3 = 95. Or 97-2 = 95 (These will be same always).
Now append 95 and 06. Thus the answer is 9506
Let's see one more example of this type that produce carry during multiplication.
88*91 = ?
88 12
91 9
------------
80 08
12*9=108 (Simply 120-12). Write '08' and '1' is the carry. Now 88-9=79 (Or 91-12=79).
Add the carry to 79 which gives 80. So the answer is 8008.

How to multiply integers?
Integers are simply "whole" numbers such as 0,1,2,3 and so forth (as opposed to 1.5 for instance). To multiply integers we either have to know our times tables or know how to make use of a computer. To know both is preferable.If, as an absolute minimum, you learn the times tables for all the 10 digits (up to and including times 9 for each one) then you will be able to multiply any two integers (within practical limits). In fact you will be able to multiply any 2 rational numbers. You might need to use a pen and paper but, given enough time, you could do it.Otherwise, you can use a computer (such as a calculator) to do the work for you. Of course, one should not solely rely on computers and should be able to make calculations, such as these, unaided when required.The only other piece of information you need to know for the multiplication of integers is that whenever you multiply two numbers with the same sign (i.e. two positive or two negative numbers) the result will be a positive number. Whenever you multiply two numbers with different signs (i.e. a positive and a negative number) the result will be negative.
How much would 5438 paper clips weigh?
I would suggest you get a sample of 100 paper clips (count them), weigh them, then multiply the result with 54.38. If the weight of the 100 paper clips is too low to get an accurate reading, count off a larger number, and weigh them. In this case, of course, you would have to multiply by a smaller factor.
