Question

ok so i just dont get what an integer is. and why are there the 2 lines between them like this l2l ok ill give you one problem as an example. it says write this as an integer:

6 degrees below zero...plz help me solve this one and ill try to get used to the other ones

and theres another one thats 2,000 ft above sea level. plz help! im in desperate need and i need to finish this so dont tell me to ask the teacher!

Answer 1

The first one would be -6, and the second one would be 2000

Answer 2

interger just means a whole number (trust me) so -6

but the other question you didnt explain so well

Answer 3

An integer is a positive number, negative number, or 0.

The 2 lines around a number like l2l means "the absolute value of 2". Absolute value is always positive. Absolute value is how many units that number would be from 0 on a number line. For example, if the problem was l2l then the answer would be 2, because 2 is 2 units from 0. Another example, if the problem was l-2l then the answer would also be 2, because -2 is also 2 units from 0.

6 degrees below zero= -6 degrees

2,000 ft above sea level= 2, 000 ft above sea level

Hope this helps!

Answer 4

An integer is a whole number - meaning no decimal places.

so as your other helper here says -

6 is a whole number so below zero = -6 (minus 6)

2,000 feet is already a whole number and as it is above sea level it is 2,000 feet (NOT a minus)

Answer 5

6 degrees below zero is -6

and the other is just 2,000

a number is negative if it is below zero or a loss.

A loss of ten pounds (-10)

Withdraw $100 (-100)

Below sea level is a negative, b/c if zero is sea level below it is the negatives and above is the positives.
