100 x 23 = 2300 (If timing by 10, simply add a zero. If by 100, add two zeroes.)
Some people add milk first and tea second, others add the tea first. So why not?
The lowest number you could add to make it divisible by 10, 2, and 5 would be 7. 23 + 7 = 30 30/10 = 3 30/2 = 15 30/5 = 6 Also, technically, you could add (-3) to make 20. 23 + (-3) = 20 20/10 = 2 20/2 = 10 20/5 = 4 Basically, you could add any number to 23 that would get a multiple of 10, since 2 and 5 are both factors of 10 to begin with.

If Theresa's age is 23 and you add on another 10, the answer is 33.
3, 13 and 23 are prime numbers.

30 / 2 + 10 - 2 = 23
well if you add together 2 and 2, it makes 4 so ,10 add 10 is 20 ,so double 20, is obviously 40.
