4 x 9 = 36 9 - 4 = 5 Therefore, the two numbers are 9 and 4. Similarly, -9 and -4 can be multiplied together to make 36, and have a difference of 5.

[(4x5)/2] - 9 = 1
There are 5 numbers which can make the 3 digit numbers in this example. Therefore each digit in the 3 digit number has 5 choices of which number can be placed there. Therefore number of 3 digit numbers = 5 x 5 x 5 = 125
4 x (5 x 3 - 2 x 1 )
4 x 9 = 36 9 - 4 = 5 Therefore, the two numbers are 9 and 4. Similarly, -9 and -4 can be multiplied together to make 36, and have a difference of 5.

There are 5 numbers which can make the 3 digit numbers in this example. Therefore each digit in the 3 digit number has 5 choices of which number can be placed there. Therefore number of 3 digit numbers = 5 x 5 x 5 = 125
4 x (5 x 3 - 2 x 1 )
To find the median of a set of numbers write them in order, then: * if there are an odd number of numbers then the median is the number in the middle * otherwise there are an even number of numbers and the median is the mean average of the two numbers in the middle. With 4 numbers there is an even number of numbers, so the median is the mean average of the 2nd and 3rd numbers when they are sorted into order. Example: Find median of {3, 9, 4, 5} Ordered → {3, 4, 5, 9} → median = mean_average(4, 5) = (4 + 5) ÷ 2 = 4.5
Yes. 0, 4, 8, 13572, 96

The rearrangement of 5 figure numbers will be 5x4x3x2x1 which is 120 combinations, when you don't repeat a number.
