In any division sum, such as 8 / 4 = 2, the number to be divided, in this instance, the 8, is the dividend.
Arrange the numbers in order of size (increasing or decreasing). The median of all eight is the mean of the fourth and fifth. The mean of the two numbers is their sum divided by two.
Sum of 8 and 4 (8+4=12) is 12 Difference of 8 and 4 (8-4=4) is 4 So 12/4 is 3

Oh, what a lovely math question we have here! To find the expression for 8 minus the sum of 5 and 43 divided by 8, we first need to calculate the sum of 5 and 43, which is 48. Then, we divide 48 by 8 to get 6. Finally, we subtract 6 from 8 to find the answer, which is 2. Happy little calculations!

In any division sum, such as 8 / 4 = 2, the number to be divided, in this instance, the 8, is the dividend.
The mean average of a set of numbers is the sum of the numbers divided by how many of them there are. If there are 8 numbers with a sum of 2464, their mean average is 2464 ÷ 8 = 308.
Arrange the numbers in order of size (increasing or decreasing). The median of all eight is the mean of the fourth and fifth. The mean of the two numbers is their sum divided by two.

2 x 6 + 0 = 12 2 x 1 + 2 = 4 4 is not [divisible by] 8, so 60 is not divisible by 8. (The remainder when 60 is divided by 8 is 4). To test divisibility by 8: Add together the hundreds digit multiplied by 4, the tens digit multiplied by 2 and the units (ones) digit. If this sum is divisible by 8 so is the original number. (Otherwise the remainder of this sum divided by 8 is the remainder when the original number is divided by 8.) If you repeat this sum on the sum until a single digit remains, then if that digit is 8, the original number is divisible by 8 otherwise it gives the remainder when the original number is divided by 8 (except if the single digit is 9, in which case the remainder is 9 - 8 = 1).
The average is 8. The sum is 3 + 5 + 16 = 24, divided by 3 is 8.
8 / (5 + a) Example: if a = 3 then 8 / (5 + 3) = 8 / 8 = 1 / 1 = 1
