How to find the product of the digits of a number?

Given a number, the task is to find the product of the digits of a number. Recommended: Please try your approach on {IDE} first, before moving on to the solution. Get the rightmost digit of the number with help of remainder ‘\%’ operator by dividing it with 10 and multiply it with product.

How do you sort between 2 and 3 digit answers?

A good starting point would be to sort the 2 and 3-digit answers into lists or they may decide to identify the reversed numbers that give a 2-digit answer on the hundreds board. Share patterns. Is there a pattern in the numbers that give 3-digit sums?

How do you introduce a reversed 2 digit problem?

Introduce the problem – you could do this by writing 2 reversed 2-digit numbers eg 14 and 41. Ask the students what they can tell you about the 2 numbers. If they identify that the digits have swapped places then introduce the problem.

The sum of the digits of a two-digit number is 8. When we interchange the digits, it is found that the resulting new number is greater than the original number by 36. What is the 2- digit number? Solution: The number is 26. How did i get this? x+y = 8 … (1) y-x = 4 … (2) Add (1) and (2): 2y = 12 or y = 6, hence x = 2. Let the number be XY.

What is the result when we interchange the digit?

When we interchange the digit it is found that the resulting new number is greater than the original number by 27. What is the two digit number Let the digits at tens place and ones place: x and 9−x respectively. Now Interchange the digits: Digit at ones place and tens place: x and 9−x respectively.

What is the number formed when the digits are reversed?

Let x be the digit at unit’s place and y be the digit at ten’s place. Since y is at ten’s place, then the number formed is 10y+x. By reversing the digits, it becomes 10x+y.
