When you add a number and its additive inverse, for example x+(-x), you would get 0 as an answer no matter what the number is. When you multiply a number and its reciprocal or multiplicative inverse, for example x*(1/x), you would always get 1 as an answer.
you would convert the mixed numbers into fractions where the top number is greater than the bottom number, then multiply both the numerator and the denominator by a number that makes the denominators the same.

Compatible numbers are numbers that are close in value to the actual numbers and easy to add, subtract, multiply, or divide mentally.So a logical compatible number for 77 would be 80.
There are infinitely many pairs of numbers that will add to 105.8 and infinitely many pairs of numbers that will multiply to 105.8 but there are no pair that will add AND multiply. I do not think there are larger sets, but I could be wrong. One example of a triplet adding and multiplying to the same number is 1, 2 and 3. They add to 6 and multiply to 6.
Multiply the number by 100 and add a percentage sign.
If the base numbers or variables are the same, you add the exponents.
If you add, subtract or multiply rational numbers, the result will be a rational number. It will also be so if you divide by a non-zero rational number. But division by zero is not defined.

There aren't any whole numbers that satisfy these conditions. The only numbers that multiply to 23 are 23 and 1.
