### What is the difference between adding and subtracting integers to multiplying and dividing integers?

The difference between adding and subtracting integers to
multiplying and dividing integers comes by the sign conversion.
For eg, there are two sets of integer -4 and -2 and -4 and 2
.
Lets add and subtract and find the result .
addition : -4 +(-2) = -6.
subtraction :
-4 -(-2) = -2.
Multiplication : -4 *(-2) = 8.
Division :
-4 /(-2) = 2.
On the other hand,second set
addition :
-4 +(2) = -2.
subtraction :
-4 -(2) = -6.
product :
-4 *(2) = -8.
division :
-4 /(2) = -2.

### What is an inverese in algebra?

An inverse is another word for opposite. The inverse for adding
is subtraction, multiplication is division, etc. If you are solving
an equation, and have to get a variable alone, you must eliminate
any other numbers with the variable, which means undoing the
operation (x, +, -, /); so you perform the inverse.
Example:
x + 3 = 9.
Subtract 3 on both sides to get x alone, because subtraction is
the inverse of addition:
x = 6.
Example:
2x + 3 = 9.
You must do the inverse of addition and subtraction before the
inverse of multiplication and division. In this case, after
subtracting 3 you have:
2x = 6.
x is being multiplied by 2, so the inverse is division, and your
answer is x = 3.

###### Asked in Computers, Ancient History

### How was calculations done during ancient times?

Essentially by counting. Addition and subtraction were known
more than 4000 years ago. The logic of multiplication and division
were also known, but were performed by either adding or
subtraction.
Modern arithmetic was not possible until the invention of
positional notation and the concept of zero came into being ...
usually ascribed to Arab mathematicians.

### What is the largest value of roman numerals?

M=1000, D=500, C=100, L=50, X=10, V=5, I=1
But larger values can be obtained by adding brackets and
superscripts to these numerals.
For example: (M)(M) = 1,000,000,000,000 or 1*1012 in standard
form
Numerals in brackets indicate multiplication by a thousand and
superscript numerals indicate multiplication by that particular
numeral.

### What is the definition of order of operations?

The definition of order of operations is to use the
P.E.M.D.A.S.strategy. P.E.M.D.A.S. means Parentheses, Exponents,
Multiplication, Division, Adding, Subtracting. You have to use them
in order. If there are no parentheses, see if there are any
exponents if not move on to the next letter. HERE IS AN EXAMPLE.
You use these operations and use them in order. That is why it is
called order of operations
(30-3) / 3=9
I subtracted what was in the parentheses which was 27 then I
divided it by 3. Three times 9 equals 27, so the answer was 9.
Also, if there is multiplication or division or even both, do
multiplication first. If there is just division do that first then
just go by the order. HERE IS AN EXAMPLE
3+17*5=88
i did the multiplication first which was 17*5 and I got 85 + 3
and my answer was 88.
----------
The order of operations is an order in which you do operations
(i.e. Parentheses, Exponents, Multiplication, Division, Addition,
and Subtraction). PEMDAS is a good way to remember the order, but
for multiplication & division as well as addition &
subtraction, it doesn't matter if division comes before
multiplication or subtraction comes before addition, as long as you
are doing the problem from left to right for
multiplication & division and left to right
for addition and subtraction.
For example:
2 x 6 + 3 x 2 / 3 - 2 + 14
First you'd do 2 x 6, which is 12, and then 3 x 2, which is 6. 6
divided by 3 is 2. Then you have to go back and add 2 to 12, as we
skipped over the addition sign between the 6 and 3 to begin with. 2
+ 12 is 14. Subtract 2 and you get 12, and add 14 and you get 26.
This got a little messy, as you have to hop around to get all the
operations done in order, but the order of operations requires you
to do the operations this way. 26 would be your correct answer.
