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

Do two negative integers equal a positive?
Only when you divide or multiply.
Is the product of two positive integers always positive?
No the product of two integers will not always be a positive, because if you multiply a positive and a negative you'll get a negative.
Is the product of two integers always positive explain?
Yes, because if you were to multiply -36 by 4 the answer is 108, I think.
How does the method for solving equations with fractional or decimal coefficient and constants with the method for solving equation a with integer coeffients and constants?
Fractional u multiply and decimal u multiply and integers u minuse or add them
What is the sum of the first 100 positive integers?
To find the sum of the first 100 integers, you first add 1 plus 100 (the first and last numbers of the set) and get 101. Do the same with the next two integers, 2 and 99 and you'll get 101. Since you are adding two integers at a time and there are 100 integers between 1 and 100, you'll get 101, fifty times. Therefore, a shortcut would be to simply multiply 101 times 50 and get 5,050.
What happens when you add sutract multiply and divide integers?
When 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.
How do you find a product of a integers?
Multiply them.
Does product mean add or multiply?
Product= the total of two integers multiplied together Sum= The total of two integers added together
Why is it important to know how multiply and divide integers?

What can you do with integers?
you can add subtract multiply and divide them.
How do you multiply three integers?
You multiply the first two. Then you multiply the result with the third number. Actually you can multiply in any order.
How do you multipy integers?
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.
How do you multiply 3 negative integers?
=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.=
What happens with the numbers when you multiply and divide integers?
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.
What happen when you multiply two positive integers?
you get an positive answer ex +2 multiply +2= 4
How do you multiply and dive decimals and integers?
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
What are two consecutive integers of 156?
Two consecutive integers which multiply together to equal 156 are 12 and 13.
