0+1=1
0.1+0.9=1
0.2-0.1=1
Just multiply the first three prime numbers together.
4 and 5 5 and 6 6 and 7
Add them together, divide that total by three
There are multiple ways to add three numbers together to get a sum of 17. One possible combination is 5 + 6 + 6, another is 9 + 4 + 4, and yet another is 7 + 5 + 5.
5 and 10 10 and 15 5 and 15
It means write down three pairs of numbers that are relatively prime like 4 and 9, 5 and 6, 13 and 25
The three pairs of numbers that each add up to 7 are (1, 6), (2, 5), and (3, 4). In each pair, when you add the two numbers together, the result is 7. These pairs are examples of complementary numbers that combine to equal a specific sum, in this case, 7.
3 and 5, 4 and 6, 8 and 12
Just multiply the first three prime numbers together.
There are three pairs.
nine (Three pants per blouse; 3 x 3 = 9.)

81 has three factor pairs: 81,1 27,3 9,9
The number 18.
81 As there are no limits stated then you can have a number comprising a repeated single digit (such as 2222), two pairs of numbers (e.g. 2244) or three different numbers (such as 2462). The first digit can be one of any of the 3 numbers. The second digit can be one of any of the three numbers, as can the third digit and also the fourth. Then you can have 3 x 3 x 3 x 3 = 81 different 4-digit numbers using the three given numbers.
One, two, and three.
The two numbers that have a product of 12 are 3 and 4. This is because 3 multiplied by 4 equals 12. These two numbers are factors of 12, as they can be multiplied together to result in the product of 12.
