How many ways can you add up to 12?
42 ways
We see that 12 can be written as the sum of seven different groups of three distinct positive integers. Each of these seven groups can be written in 3! = 6 different ways. Therefore, the total number of ways 12 can be written as a sum of three distinct positive integers is 6 × 7 = 42 ways.
How many 101 do you think are there if numbers 1 to 100 are paired?
The trick is realizing that 1 + 100 is 101, as is 2 + 99 and 3 + 98 and so on, through 50 + 51. That’s 50 pairs of numbers that each add up to 101. So the answer is 50 × 101. That’s 5,050.
What 3 numbers add up to 12 brain?
You will have 3+3+6=12.
What 3 digits add up to 14?
The possible 3-number combinations with sum of 14: 1, 4, 9.
What can make 12?
The factors of 12 are 1, 2, 3, 4, 6, and 12, because each of those divides 12 without leaving a remainder (or, alternatively, each of those is a counting number that can be multiplied by another counting number to make 12).
What is 532nd part of1004416?
NCERT Physics for Class 6. NCERT Chemistry for Class 6. NCERT Biology for Class 6. NCERT Maths for Class 7. NCERT Physics for Class 7.
What is Gauss formula?
Gauss’s method forms a general formula for the sum of the first n integers, namely that 1+2+3+\ldots +n=\frac{1}{2}n(n+1) One way of presenting Gauss’ method is to write out the sum twice, the second time reversing it as shown. If we add both rows we get the sum of 1 to n, but twice.
What 2 numbers add up to 12?
1. Add: 10 + 2 =? The sum of 10 + 2 is 12.
What three numbers add up to 12 meaning in Hindi?
The number three (3) is one more than two and one less than four. It is the first Mersenne prime. Three is an important number for many cultures (groups of people living together). It is also a prime number….3 (number)

What are the sums of 13?
1 Answer. The numbers are 6 and 7.
What two numbers add up to 13?
The sum of 9 + 4 is 13.
How do you increase the sum of a pair of numbers?
This is because when the sum is less than the required sum then to get the number which could increase the sum of pair, start moving from left to right (also sort the array) thus “l++” and vice versa. A [l] + A [r] ( -8 + 45) > 16 => decrement r.
How many combinations can you make with a set of 3 balls?
Let’s take a simpler example where you choose three balls called R (red), B (blue), G (green). There are six permutations of this set (the order of letters determine the order of the selected balls): RBG, RGB, BRG, BGR, GRB, GBR, and the combination definition says that there is only one combination!
How many combinations can you make with only one element?
You may notice that, according to the combinations formula, the number of combinations for choosing only one element is simply n. On the other hand, if you have to select all the elements, there is only one way to do it. Let’s check this combination property with our example. You’ve got the total number of objects that equals n = 12.
How to calculate the number of possible combinations of a set?
Luckily, you don’t have to write down all of the possible sets! How to calculate the combinations, then? You can use the following combination formula that will allow you to determine the number of combinations in no time: C(n,r) = n!/(r!(n-r)!), where: C(n,r) is the number of combinations; n is the total number of elements in the set; and
