(2 + 9) x 4 - 1 = 43
43 is a prime number. So, 43 can only be produced as a product of 1 times 43.
If you are not concerned with the numbers being round, then there are an infinite number of answers to this. If, on the other hand, you want to stick to round numbers, then there are very few answers: 1 * 43 -1 * -43 43i * -i -43i * i If you only want real integers, then you're down to two answers: 1 * 43 -1 * -43 And if you only want natural numbers, then there's only one answer: 1 * 43 This is because 43 is a prime number, and has no factors.

If you are trying to reduce a fraction, 43/100 for example, then you've gone as far as you can. Forty-three is a prime number and cannot be reduced further. (Prime numbers are numbers that have no factors but 1 and the number itself. The only numbers that will divide into 43 are 1, and 43.) Ways to express this number are 0.43 or 43 % or 43/100.
Since both 23 and 43 are prime numbers, their only common factor is 1.
43 is a prime number, only 1 and 43 can go into it
43/200 is reduced because the only common factor of the two numbers is 1.
