operations with signed numbers
combining terms
I'm working with numbers, question as :
5 + 8 = 13
7 - 4 =3
are straight forward. However if a question such as "6 - 9 =" presents itself we have a problem.
Let's examine this problem in terms of money. What if you had $6.00 and i had to pay out $9.00you would have to go into debt by $3.00. in other words you would still owe $3.00 (after giving up the $6.00 had). We will write this as -$3.00 using a minus in front of the number 3.

There for (...) 6 - 9 = 3
Ex. The following question can be read as :
2 - 6
2 - 6
*i have 2 * *and i owe 6*
combining these, results in owing 4.
There for (...) 2 - 6 = -4
Ex. How could we interpret the following?
combining these, results in owing 4.
There for (...) 2 - 6 = -4
Ex. How could we interpret the following?
-3 + 5 =
ANSWER : i owe 3 and i have 5. The result is I have 2.
There for (...)
-3 + 5 = 2 or +2
There for (...)
-3 + 5 = 2 or +2
Any amount that i have is a whole number or a number with a plus sign in front of it. this is Known as a POSITIVE NUMBER (+)
Similarly, any amount that i owe would be written with a minus sign in front of it. Such a nimber is known as a NEGITIVE NUMBER.
The number zero (0) is a considered to be neither. Each item, whether it be an amount we have (positve value) or an amout we owe (negitive value) is called a Term. these question are all about Combining terms to come up with the end result.
Once again i had nothing better to do =/
