# How will you know the exponent of scientific notation is negative or positive?

The smaller number at the top right of the ten may or may not have a negative sign in front of it: like 6.2 x 102 or 6.2 x 10-2. If the little number is positive, the decimal in the first number will move to the right. If the exponent is negative, the decimal in the first number will move to the left.

### what to do with a negative exponent why is this important?

The negative exponent is simply the reciprocal of its positive value. For example, a-b = 1/ab It is particularly important wherever scientific notation is used. The negative exponent is simply the reciprocal of its positive value. For example, a-b = 1/ab It is particularly important wherever scientific notation is used. The negative exponent is simply the reciprocal of its positive value. For example, a-b = 1/ab It is particularly important wherever scientific notation is used…

### How do you write 10.4 in scientific notation?

It took me forever to learn scientific notation because of how the exponents seem backwards. When you move the decimal to the left (towards the negative numbers in a line) your exponent will be positive. When you move the decimal to the right (towards the positive numbers in line) your exponent will be negative. So since we need a number between 1-9 in order have scientific notation we have to move our decimal one place…

### How do you convert scientific notation to ordinary notation?

Scientific notation is a way to express either a very large, or a very small number. 10x5.34 is an example of scientific notation. So, move the decimal point to the right (since there is a positive exponent). It then becomes 53,000. If there is a negative exponent, move the decimal point to the left instead of the right. 10x4.6-3 would become 0.0046.
