What is a additive inverese?
The additive inverse of a number is the value that, when added to the original number, results in zero. For any real number ( a ), its additive inverse is ( -a ). For example, the additive inverse of 5 is -5, because ( 5 + (-5) = 0 ). This concept is fundamental in mathematics, particularly in solving equations and understanding properties of numbers.
Why does K represent 1000?
The 'K' stands for 'kilo,' as in kilograms. It's derived from Greek.When you put a 'K' after any number, it is multiplied by 1000.
What is an inverese in algebra?
An inverse is another word for opposite. The inverse for adding is subtraction, multiplication is division, etc. If you are solving an equation, and have to get a variable alone, you must eliminate any other numbers with the variable, which means undoing the operation (x, +, -, /); so you perform the inverse. Example: x + 3 = 9. Subtract 3 on both sides to get x alone, because subtraction is the inverse of addition: x = 6. Example: 2x + 3 = 9. You must do the inverse of addition and subtraction before the inverse of multiplication and division. In this case, after subtracting 3 you have: 2x = 6. x is being multiplied by 2, so the inverse is division, and your answer is x = 3.
