# Product of 10 numbers

• 3
• Locked
Do you think you can easily multiply ten consecutive numbers from 1 to 10 in your mind? If this seems easy to you, you've probably never tried it. Here's a hint: the product is not a small number; it's more than three million. But this is easy for a computer: the important thing is to tell it how to do it.

Just multiply 1-10 inside System.out.println();

No loop is needed , just println

Did it with a for-loop. My result was correct however it said that the last two tasks, - The displayed number should be more than three million. - The displayed number must match the task conditions. are not correct. Used a simple println method and then it worked. No idea why the loop didn't work although the result was the same

Simple, do not multiply 10 number at once but x = 1 * 2 * 3 ; y = x * 4 * 5 * 6 etc.

I am getting an output of 9864100. Incrementing i in the for loop: for(int i =0;i<=10;i++) int z is the product z*=i and then incrementing z. Printing out the output (z) outside the for loop. My code still fails the last task condition. Please help debug what I am doing wrong

Please post your question with the attached solution in the section Help. 1*2*3*...*10 = 3 628 800

best to use factorial to solve this problem

I think recursion is a better way to solve the problem
