INTEGERS IN THE EVERYDAY LIFE

Three examples of how integers can be used in real life is the stock market, temperature, and money (withdraw and deposit).You can use integers in the stock market because the stocks can either be high or low, positive and negative.You can use integers in temperature because the temperature can be positive numbers which means that it can be cold but its warmer than the negative numbers where its colder than normal.You can use integers in the bank because you can withdraw and deposit money.When you are in debt your account can be in the negatives.This is how integers can be used in real life.

my understanding of integers:
integers are whole numbers that can be positive or negative. 0 is a whole number but its neither negative nor positive.you can add, subtract,multiply and divide integers.when subtracting you are actuALLY ADDING. WHEN YOU ARE ADDING YOU ARE ACTUALLY SUBTRACTING.YOU CAN DETERMINE THE SIGN BY WHICH EVER NUMBER HAS A GREATER VALUE WITHOUT ITS SIGN.WHEN YOU MULTIPLY AND DIVIDE YOU DO IT NORMALLY EXCEPT TO DETERMINE THE SIGN THE IS HOW YOU KNOW: -X+=-,-X-=+,+X-=- AND -/-=+,-/+=-,+/-+- THIS IS HOW YOU DETERMINE THE SIGN WHEN YOU MULTIPLY AND DIVIDE INTEGERS.INTEGERS ARE ONLY WHOLE NUMBERS,IT CANNOT BE A FRACTION OR A DECIMAL.THIS IS MY UNDERSTANDING OF INTEGERS.
