How Many Ways to Make 10
There are many ways to make 10, and we're here to show you how.
1 + 9
The first way to make 10 is simply by adding 1 and 9 together. They both equal 10, so you don't need to divide them or multiply them. The second way is actually the same as the first one, but with some minor differences in how you add them. The third way uses subtraction instead of addition, which makes it a bit more challenging than the other two methods but still easy enough for kids to do on their own once they've mastered basic math skills like counting and addition.
2 + 8
2 + 8 = 10
This is one of the simplest ways to make 10, and it's a favorite among children. The trick is adding two numbers together. In this case, 2 plus 8 equals 10!
3 + 7
There are four basic operations that can be performed on integers: addition, subtraction, multiplication and division. Addition is not commutative (the order of the numbers being added does not matter), but multiplication and division are both commutative (3+4=4+3).
Subtraction is the inverse of addition i.e., it reverses the direction of travel when working with numbers. For example: 5-2=3; 10-5=5; 100-10=90; 1000-100 = 900.
Multiplication involves adding together two or more numbers i.e., 5 x 3 = 15; 10 x 1 = 20 etc. Multiplication is not commutative — 3 x 4 ≠ 4 x 3 because in each case there are different factors being multiplied together at different places within an expression to get final result as shown above where we have written down two possible answers which can be obtained by multiplying variables together depending upon whether we write down 3!! or 4!! first followed by writing down 2! afterwards so what?!..
4 + 6
There are many ways to add 4 and 6.
Add 4 and 6 together: 10
Add them separately: 4 + 6, or 46 (with spaces).
Add the numbers in different orders: 41 + 59, or 43 + 99.
5 + 5
You can make 10 from 5 + 5.
You can make 10 from 5 + 6.
You can make 10 from 5 + 7.
You can make 10 from 5 + 8.
You can make 10 from 5 + 9.
You can make 10 from 5 + 10
7 + 3
You can make 7 + 3 equal 10 in a number of ways. If you add three to seven, the result is 10. For example:
7 + 3 = 10
7 + 3 = 10
7 + 3 = 10
8 + 2
The first way to make ten is the same as the second, third and fourth ways, but with a different first step. The first step is 1+2=3 (1-2=1). The second step is 3*10=30 (1+2=3). The third, fourth and fifth steps are 30/10=3 (1+2=3); 3 + 2 = 5; 5 + 1 = 6; 6 - 2 = 4; 4 + 3 = 7; 7 + 2 = 9; 9 - 2 = 7.
9 + 1
9 + 1 = 10. This is the first time we've seen a sum that equates to a multiple of 10, and we can see that it's an even number because it has no odd digits. In fact, most numbers are even—even though there are more multiples of 2 than any other number (50), there are still more multiples of 3 (60), 4 (40), 5 (30) and 6 (20). Even numbers always have two factors: 1 and itself. An odd number, on the other hand, has only one factor: itself.
10 is also a prime number because it isn't divisible by any smaller integer except for 1 or itself; in this case 10 divided by 2 gives 5 which is not part of our original set. Since we can't divide by anything else without getting an answer greater than 0 or less than 0, this makes 10 prime! Prime numbers are often thought to be fundamental building blocks for other types of math beyond arithmetic—for example proving Euclid's famous theorem involves prime numbers among other things—but exactly why they're so important remains unknown today despite centuries worth of research into the topic."
There are a lot of ways to make 10
There are a lot of ways to make 10. For example, you could add 9 plus 1, or 8 plus 2, or 7 plus 3, etc. This is called addition because it adds the numbers together to get a total. The total for each operation is called the sum of those operations.
In this lesson we will be learning about another way to make 10 which is called subtraction because it subtracts one from another number and gets rid of it altogether!
While this article has covered a lot of the important ways to make 10, there are many other methods out there. If you know of any that we didn't mention, feel free to post them in the comment section below!
