0 1 2
Because numbers on the number line are in ascending order and -2 is closer to 0 than is -10
The only prime number from 2 to 0 is 2.
You could draw a number line from 0 to 10 and fill in the integers 1, 2, 3, 4, 5 and so on. Draw the same number line but make it from 0 to 1 and label the numbers 1/10, 2/10, 3/10 and so on. Make a mark at 5 and 7
point on the number line is greater than 0 but less than 2 = 1

the line which divides the number into 2 equal halves is called symmetry in numbers example:- in digits 0 to 9 the symmetry of numbers are 0, 1, 3, 8.

Integers are WHOLE numbers, like 3, 18, 34, and 256. Rational numbers are any numbers which can be expressed as a ratio of two integers - 3/4 is a rational number. 124.45 is a rational number. In other words, rational numbers INCLUDE all integers. Fractions are Rational numbers.The natural number line starts at 1, and goes up by 1 each time. 1, 2, 3, 4, 5...The whole number line includes the natural, but starts at 0. 0, 1, 2, 3, 4, 5...The integer number line includes the whole number line, but adds its negative counterparts. ...-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5...The rational number line includes the integernumber line, but includes fractions (where the numerator is an integer and denominator is a non-zero integer.) ...-1, -1/2, 0, 1/2, 1...
int main() { int numbers[10]; int j; for (j=0; j<10; j++) { scanf("%d", &number[j]); } printf( "%d %d\n", number[0], number[1]); printf( "%d %d\n", number[2], number[3]); return 0; }
Any two numbers the same but one is negative. For example, -2 and 2, -68 and 68, -4968 and 4968, etc.
Rational numbers are infinitely dense and so there is no such number. If for example, you considered F1 to be the fraction that was closet to 0 then what about half that number? F2 = (F1)/2 is closer to 0. And then what about F3 = (F2)/2? This could go on for ever.
A number line always starts at zero. The numbers to the right are ordered in sequence and are positive whole numbers. EXAMPLE: 0 1 2 3 4 are positive numbers. The numbers to the left of zero are negative. EXAMPLE: 4 3 2 1 0 The order the numbers are in is just like you would count normally. Negative 4 3 2 1 0 1 2 3 4 Positive

The only prime number from 2 to 0 is 2.
The absolute value of a number is the distance the number is away from 0. For example, on the number line 2 is 2 units from 0 So |2|=2. But, -2 is also 2units away from 0 on the number line, so |-2|=2 as well. In general for any real number x , |x| is the distance from x to 0 on the number line. That helps us see why if x is a negative number, the distance from zero must still be positive. So for x<0, |x| is -x. For example, if x is -2, the absolute value is -(-2) which is positive 2. In general is a and b are real numbers |a-b|=|b-a| and both are the distance between a and b. Now let a =0 and we have |-b|=|b|
2, if you're considering only positive numbers (numbers greater than 0) 0, if you're considering only non-negative numbers (numbers greater than or equal to 0) If negative numbers are allowed, then there is no smallest even number
