If by "between", you include the edges, there are only -2, -1, 0 and 1 (4 numbers). For more, include any fractions you want.
One plus one is 2. Or in numbers.. 1+1=2..
There is an infinite number of numbers between 1 and 2.
The range of that set of numbers (the difference between the highest and lowest number) is 11.
3-cubed plus 2 plus 1 plus 4= 34
No, there are more irrational numbers between 1 and 2 than there are rational numbers.
No, not at all. There are more irrational numbers between 1 and 2 than there are rational numbers in total!
-1
To find the mean (or average) you first add up the numbers you have. NOTHING 1.88
The sum of the numbers given is 31. 1 + 2 + 4 + 8 + ... + 2n = 2n+1 - 1
500,000,500,000 is the answer.
-2
They can be: 1 and 1/2 plus 1 and 1/2 = 3
