1. scientific nota- the scientific system of writing numbers
tion -composted of 3 parts: mathematical sign, the significand, and the exponen-
tial/logarithm
2. mathematical designates whether the number is positive or negative (+/-)
sign
3. significand the base value of the number or the value of the number when all the values of
ten are removed
4. exponential/loga- a multiplier of the significand in powers of 10. a positive exponential multiplies the
rithm significand by factors of 10. a negative exponential multiplies the significand my
factors of 1/10
