Two (or four) digits added together cannot equal 42. Two-digit numbers multiplied together cannot equal 82.
32 x 32 = 1024
A two digit number whose two digits added together equal 42 and multiplied together equal 82
I think you r cheating Mr.Cheater
The answer is vague but correct . Take any two prime numbers whose combined digit length is 501 and their product will generate a 500 or a 501 digit number.
A decimal number is multiplied by a non-decimal number the same way any two numbers are multiplied together. The place value of the numbers being multiplied must be kept in mind though. So if 2x3=6, just as 2x30=60, 2x0.3 would be 0.6. For numbers with more than one digit, you would treat the multiplication the same way as for non decimal numbers.
2 digit number
456 and 24
Any prime numbers of about 66 or 67 digits will do.
They all have the digit 9 in their number and are all the sum of other numbers multiplied together. 791 = 7x113 793 = 13x61 891 = 3x3x3x3x11 984 = 2x2x2x3x41
Two consecutive two digit numbers that when multiplied give the product of 812 are 28 and 29.
