21 is an integer and not a fraction. However, it can be expressed in rational form as 21/1.
No. The square root of an integer is either an integer, or an irrational number.
To the nearest integer, 21 To the nearest ten, 20
It is a negative whole number which is the same as an integer
The positive integer factors of 273 are:1, 3, 7, 13, 21, 39, 91, 2731,3 7,13,21,39,91,273
The absolute value of the integer 21 is 21. The absolute value of something is its distance from 0.
The absolute value of 21 is 21.
absolute value is any number turned positive...so even if 21 is already positive, the absolute value is 21, the absolute value of -21 is 21 btw.
It depends. No matter what, you subtract the two quantities. If the absolute value of the positive integer is greater than the absolute value of the negative integer, your answer is positive. If the absolute value of the negative integer is greater than the absolute value of the positive integer, your answer is negative.For example:-32+11 is -21, because the absolute value of -32 is greater than the absolute value of 11, and 32 is negative.-11+32 is 21, because the absolute value of 32 is greater than the absolute value of 11, and 32 is positive.If this is all confusing, I like to remember a song my seventh grade math teacher taught the class to the tune of "row row row your boat:"same sign add and keepdifferent sign subtractkeep the sign of the larger numberthen you'll be exact!"(the word "sign" refers to negative or positive)
21 is the absolute value of 21 because it is 21 numbers away form 0.
An example of an integer is... - 4 is the opposite of 4, 21 is the opposite of - 21.
+21 and -21
Yes it is a negative integer
It is 40 because -19+40 = 21
21 is an integer which is also a rational number because it can be expressed as a fraction in the form of 21/1
negative means opposite therefore -(-21) = 21 so your answer is 21
