What is the first negative number?
There isn't any. For any negative number you can think of, no matter how small it is, I can always give you a negative number that's smaller than your number. There's no 'first' one.
How can you tell if a number written in scientific notation is big or small?
In scientific notation, a number is expressed as a decimal multiplied by a power of 10. To determine if a number is big or small, look at the power of 10. If the power is positive, the number is big, and if the power is negative, the number is small. The higher the magnitude of the power, the larger or smaller the number.
What happens when you add a positive with a negative?
It depends on what numbers. In general, subtract the small number from the big number, and the if the big number was negative, put a negative sign in front. If positive, put a positive sign.10+-6=4-10+6=-4or, disregard the plus and put positive first.10-6=46+-10= 6-10=-4Just put the values together
