The sum of the digits of a two digit number is 16 If the digits are reversed the new number is 18 less than the original number Find the original number?
In most simple problems like this, I prefer to solve it directly instead of using algebra. If the sum of the digits is 16, the digits can be 7 and 9, 8 and 8, or 9 and 7. So all we have to do is reverse the digits of 79, 88, and 97, to see which reversed number is 18 less than the original. But it should be pretty clear that we don't actually need to do that to all 3, because 97 is the only one that will get smaller by reversing the digits. I'm pretty sure by now that the answer is 97, but to be sure let's reverse the digits and check if the difference is 18: 97-79=18. Yep, 97's the answer! This could also be solved using algebra, like they probably wanted you to do: We'll use T for the tens digit and U for the units digit. Given T+U=16 and 10T+U-18=10U+T, solve. U=16-T 10T+16-T-18=10(16-T)+T 9T-2=160-9T 18T=162 T=9 U=16-9=7 So the original number was 97.

In algebra How can 0 1?
Well, in science you always need significant digits: 0 has no significant digits, so we round to the nearest number with 1 significant digit: namely, -1 or 1.
Can you explain the 11 finger trick in detail?
The 11 finger trick is a mental math technique where you can quickly multiply numbers by 11. To use this trick, you separate the digits of the number you want to multiply by 11, add the digits together, and place the sum in the middle of the original number. This allows you to calculate the product of the original number and 11 without using traditional multiplication methods.

How can the statement be rewritten as a conditional statement in if-then form The sum of the digits of a two-digit number is less than the value of the original two-digit number.?
A) If a number has two digits, then the sum of its digits is less than the value of the original two-digit number.
The sum of the digits in a two digit number is 17 If the digits are reversed the new number will be 9 less than the original number What is the original number?
To total 17 the two digits must be 8 and 9! The original number was 98.
