intergers.?

Question

i forgot mine. i never under stood them any how.
and no math books lying around my house has the defiintions for them. wat are they wen u add subtract mutliply and diviide numbers?

Answer 1

Integers are ...-8,-7,-6,-5,-4,-3,-2,- 1 ,0,1,2,3,4,5,6,7,8... and include no decimals, or fractions or for that matter imaginary numbers. When you subtract add and divided numbers they are the 'whole number' part in the result

Examples

3 + 4 = 7 integer + integer = integer
7 - 13 = -6 integer - integer = integer
13 / 2 = 6.5 integer / integer = real number whose integer part is 6
7 * 6 = 42 integer * integer = integer

There you go!

Answer 2

Jeff A is wrong, but close. I think he knows what it is, but got the definition for whole number mixed up. It isn't what it sounds like.
Natural number: 1, 2, 3...
Whole number (starts at 0): 0, 1, 2, 3...
Integer:...-3, -2, -1, 0, 1, 2, 3...
Make sense?
All: No fractions/decimals

You add, subtract, divide, etc. to integers like you would any other number.

Answer 3

Jeff A is right, but what do you mean by "add subtract multiply and divide"? Are you asking how to do operations with integers?

Answer 4

You mean integer, not interger.

An integer is a whole number, i.e., not a fractional number, i.e., a number without decimal places.

Note that zero is an integer.
