Just multiply one pair of your numbers to give you a product, and then multiply their product by your third number.
five digits number when you multiply by four is the same the number when you reversed it is 21978*4 = 87912
by moving each digits
22 x 30
Zero!
Yes. To see if 7 and 9 are a factor pair of 63, multiply them.

the number one.
111 111 111 If you multiply 12345679 by any two digit number* where the first digit is less than 9 and the sum of the digits is 9 (eg 36), the answer will consist of a single digit repeated 9 times. This will be the first digit of the two digit number plus 1 (eg multiplying by 36 will create an number consisting of only the digit 3+1 = 4: 12345679 x 36 = 444 444 444). *Multiplying by 9 is multiplying by the "two" digit number "09", giving an answer consisting of the single digit 0+1 = 1 repeated.
Multiply 54 times 54, then move the decimal over two times, as there are 2 digits in the "tenths" place.
you multiply first then you divide
