### A good answer might be:

`243.92 = 2.4392 × 1002`

# Negative Exponents

The exponent shows by what power of `10` to multiply the mantissa by, or (the same thing) how far to float the decimal point.

`10+n` means move the decimal point `n` places right.

`10-n` means move the decimal point `n` places left.

1.82371 | × | 101 | = | 1.82371 | × | 10 | = | 18.2371 | (move the point 1 place right)
1.82371 | × | 10-1 | = | 1.82371 | × | .1 | = | .182371 | (move the point 1 place left)
1.82371 | × | 102 | = | 1.82371 | × | 100 | = | 182.371 | (move the point 2 places right)
1.82371 | × | 10-2 | = | 1.82371 | × | .01 | = | .0182371 | (move the point 2 places left)
