7 x 2 is 14.

If you have blocks or pennies at your house, gather 14 of them. Try sorting them into pairs of 2. You will end up making 7 pairs of 2. When you stand back, you will see that if you have 7 pairs of 2. Now, count them up. There will be 14 total because if you have 7 groups of 2, that is the same as 7x2= 14.

Now, try to resort the same 14 objects into groups of 7. How many do you think you will have? 2! You can reverse the numbers in a multiplication problem and the answer will stay the same. It is called the commutative property.

2x7=14

AND

7x2=14

Another way to think about "7 times 2" is to think of it in terms of tangible real-world objects. Here are a couple of examples:

Example 1 - Suppose that you initially have only $2 and someone gives you an extra $12. Ultimately, you now have a total of $14. You now have "7 times" as much as you started with. In other words, you have a "7-fold" increase in the amount of money that you started with or $2 x 7 = $14.

Example 2 - Suppose that you initially have $7 and someone gives you an extra $7. Ultimately, you now have a total of $14. You now have "2 times" as much as you started with. In other words, you have a "2-fold" increase in the amount of money that you started with or $7 x 2 = $14.

I hope that you can see the commutative property at work ( 2 x 7 = 7 x 2 ) when you are dealing with real life objects. In this case, we are dealing with money.

I hope that this helps.

7 times 2 is 14.

One way to understand multiplication is as repeated addition. Here we would have 7 groups of 2 or 2+2+2+2+2+2+2=14. Since the multiplication operation is commutative (axb=bxa) we could also see this as 2 groups of 7 or 7+7=14.

It will be easy if you think of 7 x 2 as 7 added twice or 2 added 7 time.

7 x 2 = 7 + 7 = 2 + 2 + 2 + 2 + 2 + 2 + 2

If you add those up they should all equal 14.

In order to know what's 7 times 2,  we can use the method of multiplication as well as addition to know the answer. 

By using multiplication we simply turn this into equation form first to make it easier to comprehend and therefore solve.

Here, 'what' can be termed as 'x', so the equation would be:

 `x= 7*2`

`x=14`

To make this more comprehensive we can use the addition method.

2 + 2 +2 + 2 + 2 + 2 + 2

=14. 

Hence, the answer is 14.

7 times 2 turned into the equation 7x2 would equal 14. However if you are ever have trouble with multiplication remember the when you are saying 7 times 2 are are also saying 7 added up twice. So you can add 7 twice see..

7+7=14

 to get the same answer as would any other multiplication problem like 5x3=15 5+5+5=15.
