If you include 00 then 10, otherwise 9.
There are no pairs of 2-digit numbers with a difference of 90 if both numbers are positive or both negative. However, with one positive and one negative, there are 71 pairs.

To multiply two digit decimal numbers, multiply the numbers as you would without the decimals. To put the decimal in the answer, count the number of decimal places in the two numbers and put the decimal in the answer that many places to the left. For example: 5.12 x 6.35 = 32.5120. If the numbers were 51.2 x 63.5, the answer would be 3251.20.
There are five numbers: 18, 36, 54, 72, 90.
No digit that is 5 places long is equal to 6 times 2 other than 12.000
Multiplying decimals is when you take two numbers with decimal points, ignore the decimals, multiply the numbers like normal, and then count the total number of decimal places in both numbers. The final answer will have that many decimal places. It's like regular multiplication, but with a little extra pizzazz.
None. 3 digit numbers are not divisible by 19 digit numbers.
With a total of 90,000 five digit numbers, we can conclude that there is 45,000 EVEN five digit numbers.
