Fast addition Okay, this is very easy. If you aren't as good at adding and subtracting, you'll be a pro at multiplying and division.

Here are some helpful hints before we go with the examples:

When you have a positive multiplied by a positive your answer will be positive because its the same thing as doing a #x# with no signs. Same as a negative times a negative.

When you have a negative times a positive your answer will be negative.

You simply JUST multiply, you DON'T due any other "easier ways", it is not like when you subtract, you need to convert the problem to an addition, same applies with addition.

SO LETS START WITH AN EXAMPLE!

Lets say you have 7X-2

First of all, lets multiply normally, simply FORGET the signs.

7X2= 14

Now you can refer back to the signs, and you know that a positive times a negative is a negative so your answer is: -14, and that's no matter how far from zero the number is

Lets try one more!

5X10

Remember their both positive so its a normal multiplication problem.

YOUR PROBLEM AND ANSWER IS: 5X10=+50

Well, you could use basic math (like 2 x 2 = 4). If you don't know these, you might want to learn them or use a calculator for right now.

If it is like 34 x 32, then you treat it like:

(30 x 32) + (4 x 32)

which is equivalent to

(30 x 30) + (30 x 2) + (4 x 30) + (4 x 2)

and I hope that you would be able to solve that.

well if the problem is like 2(integer 5) X 7(integer 2) =_________

1.You do 2Xthe integer 5=10

2.Do 7Xthe integer 2=14

3.Then you do 10X14

4.Which equals 140

0When you add, subtract, or multiply integers, you get integers. When you divide one integer by another one, you may or may not get an integer.

Multiply them.

why is it important to know how to multiply

You multiply the first two. Then you multiply the result with the third number. Actually you can multiply in any order.

you can add subtract multiply and divide them.

=when you multiply negative integers the answer is going to be negative because n-multiply by n- equals n+ but when yu multiply n+ by n- it equals n- so you basicly multiply the numbers and the answer would be ah negative.==when you multiply negative integers the answer is going to be negative because n-multiply by n- equals n+ but when yu multiply n+ by n- it equals n- so you basicly multiply the numbers and the answer would be ah negative.=

Product= the total of two integers multiplied together Sum= The total of two integers added together

You multiply or divide integers just as you do whole numbers, except you must keep track of the signs. To multiply or divide signed integers, always multiply or divide the absolute values and use these rules to determine the sign of the answer.When you multiply two integers with the same signs, the result is always positive. Just multiply the absolute values and make the answer positive.Positive x positive = positiveNegative x negative = positiveWhen you multiply two integers with different signs, the result is always negative. Just multiply the absolute values and make the answer negative.Positive x negative = negativeNegative x positive = negative.

If you multiply integers the results is an integer. If you divide integers (with one exception) the result is a rational number which, in some cases, may be an integer. However, the exception is that division by 0 is not defined.

you get an positive answer ex +2 multiply +2= 4

multiplying: you multiply like normal then if the integers are the same you get positive, if they are different, you get negative; Ex) -5x-2=+10; -5x+2=-10

Two consecutive integers which multiply together to equal 156 are 12 and 13.

add, subtract, multiply, divide

It is negative.

23 can be multiplied by an infinite number of integers.

Just multiply without the sign. Then add a minus sign to the result.

Only when you divide or multiply.

7 and 8 if you multiply them.

Nothing special. The answer is negative.

Integers

You get a product which is positive.

Exactly in the same way that you would multiply and divide whole numbers which is another name for integers

300

Multiply the integer by -1 this makes the number positive.
