Nonzero digits are always significant. (456 -> 3)\n2. Zeros BETWEEN nonzero digits are significant. (3008 -> 4)\n3. Leading zeros are NOT significant. (0.0045 -> 2)\n4. Trailing zeros AFTER a decimal point ARE significant. (12.50 -> 4)\n5. Trailing zeros with NO decimal point:\n   I wrote: \"always significant\" (1500 -> 4)\n   ** Ms. Ruiz correction: NO. In this class, trailing zeros with no decimal point are NOT significant. 1500 -> 2. If there's a decimal point at the end, like 1500., then they count -> 4. **\n\nQuiz format: 10 numbers, write how many sig figs. No scientific notation on this quiz.\n\nMs. Ruiz: \"Trailing zeros are where everyone loses points.\"\n\nNot on this quiz: sig figs in multiplication/addition (next week).\n\nLab: density of pennies, Thursday.
