What two numbers have the same sum and product?

What two numbers have the same sum and product?

The natural numbers 1,2,3 have a special property: their sum is equal to their product. 1+2+3=1 · 2 · 3. The numbers 1,1,2,4 possess the same property: 1+1+2+4=1 · 1 · 2 · 4.

Which positive integers Cannot be written as the sum of two or more consecutive numbers?

We can’t write every number as a sum of consecutive numbers – for example, 2, 4 and 8 can’t be written as sums of consecutive numbers. In the above, 9 and 15 were the only numbers that I could find that could be written in more than one way.

How many two digit positive integers are there such that the product of the two digits is 24?

There are four 2-digit positive integers whose product of the two digits is 24 (38, 46, 64, and 83).

Can you find at least one pair of integers whose sum or product is not an integer?

Answer: No. Step-by-step explanation: We cannot find a pair of integers whose sum is not an integer.

What does it mean when the product of the numbers is negative positive?

When you multiply a negative number by a positive number then the product is always negative. When you multiply two negative numbers or two positive numbers then the product is always positive. 3 times 4 equals 12. When you divide a negative number by a positive number then the quotient is negative.

How many ways can we write it as a sum of consecutive positive integers?

Some numbers can be written as the sum of two or more consecutive positive integers, and some cannot. For example, 15 can be expressed in three different ways: 7+8, 4+5+6, and 1+2+3+4+5. But it is not possible to express 8 in this way….by David Radcliffe.

Which positive integers can be represented as the sum of two or more consecutive positive integers?

In number theory, a polite number is a positive integer that can be written as the sum of two or more consecutive positive integers. A positive integer which is not polite is called impolite. The impolite numbers are exactly the powers of two, and the polite numbers are the natural numbers that are not powers of two.

How many positive two-digit monotonic integers are there?

Then as there is one decreasing monotonous number for every increasing monotonous number, I multiplied it by 2 to get 90 total 2-digit monotonous numbers.

How many positive 2-digit numbers are there?

There are 20 positive, two-digit numbers that meet the requirements. They are: 61, 63, 65, 67, 69, 71, 73, 75, 77, 79, 81, 83, 85, 87, 89, 91, 93, 95, 97, 99. There are 20 integers which meet these criteria. Not including single-digit integers prefixed with a 0, there are 90 possible two-digit integers.

Is there a pair of integers whose sum is not an integer?

No, we cannot find a pair of integers whose sum is not an integer. Because when we add a negative nor positive number we get the sum as nither negative nor positive.

What is the sum of positive integers?

The Sum of Positive Integers Calculator is used to calculate the sum of first n numbers or the sum of consecutive positive integers from n 1 to n 2 . The sum of the first n numbers is equal to:

What is the sum of consecutive integers from N to N?

The sum of the first n numbers is equal to: n(n + 1) / 2. The sum of consecutive positive integers from n 1 to n 2 is equal to: n 1 + (n 1 + 1) + + n 2 = n 2(n 2 + 1) / 2 – n 1(n 1 – 1) / 2.

What is the sum of the first n numbers?

The sum of the first n numbers is equal to: n (n + 1) / 2 The sum of consecutive positive integers from n 1 to n 2 is equal to: n 1 + (n 1 + 1) +… + n 2 = n 2 (n 2 + 1) / 2 – n 1 (n 1 – 1) / 2

How do you find the sum of all divisors of a number?

The Integers 1 to 100. It represents the sum of all the positive divisors of n, including 1 and n itself. s (N) is the Restricted Divisor Function. It represents the sum of the proper divisors of n, excluding n itself. For a Prime Number, Count (d (N))=2. The only divisors for a Prime Number are 1 and itself.
