-77 just as 77 is further from 0 on the positive side
Yes it is. It is further from zero.
Undefined: You cannot divide by zero
The additive inverse of a number is the value that, when added to the original number, results in zero. In this case, the additive inverse of -21 would be 21, as -21 + 21 equals zero. The additive inverse is essentially the negative of the original number, so the additive inverse of -21 is 21.
-21 is greater. With respect to zero, -22 is greater.
Here's how to figure these out. First, which is the biggest number (ignore the sign for now). Got it? Okay, now if it has a negative sign in front, that's your smallest number. In the list above, the biggest number does indeed have a negative sign, so it's your smallest. If it doesn't, then it's your biggest number. A negative sign turns your biggest into your smallest. The smallest number is either the positive number that is closest to zero in a list, or if the list has negative numbers, then it is the biggest negative number (that would make it the farthest away from zero).

-8 × (number + 21) = 96 → number + 21 = 96 ÷ -8 → number = 96 ÷ -8 - 21 = -12 - 21 = -33
It is a negative whole number which is the same as an integer
The statement "Negative 7 divided by 1 equals 21" is incorrect. When you divide negative 7 by 1, the result is negative 7, not 21. Dividing any number by 1 results in the number itself. Therefore, -7 ÷ 1 = -7.
The Sun has zero declination at the two equinoxes on March 21 and September 21 (approximately). At the autumn equinox in September it crosses the plane of the Earth's orbit from north to south, so its declination goes from positive to negative.
Yes. The product of an odd number (21, in this case) of negative factors will be negative; if the number of negative factors is even, the product will be positive.
There is no whole number that has that value. The nearest whole number is zero.
