Notes Sig Figs. RULES for SIG FIGS. Non-zero digits and zeroes between non-zero digits are always significant. RULES for SIG FIGS. Non-zero digits and zeroes between non-zero digits are always significant 404= 3(because the zero counts here). RULES for SIG FIGS.

RULES for SIG FIGS • Non-zero digits and zeroes between non-zero digits are always significant
RULES for SIG FIGS • Non-zero digits and zeroes between non-zero digits are always significant 404= 3(because the zero counts here)
RULES for SIG FIGS • Non-zero digits and zeroes between non-zero digits are always significant 404= 3(because the zero counts here think of a sandwich) 686 = 3 (because all regular numbers except zero…..always count)
Rules for SIG FIGS 2. Leading zeroes are not significant
Rules for SIG FIGS 2. Leading zeroes are not significant 005= 1 sig fig (leading zeroes)
Rules for SIG FIGS 2. Leading zeroes are not significant 005= 1 sig fig (leading zeroes) 0.001 = 1 sig fig (leading zeroes don’t count….start counting when you get to an actual number)
Rules for Sig Figs 3. Zeroes to the right of all non-zero digits are only significant if a decimal point is shown
Rules for Sig Figs 3. Zeroes to the right of all non-zero digits are only significant if a decimal point is shown 0.010 (2 sig figs……because of the Decimal point being there) 10 = 1 sig fig 10. = 2 sig figs
Rules for Sig Figs 4. For values written in scientific notation, the digits in the coefficient are significant 6.82 * 102 = 3 sig figs
Number 1 1234
Number 1 1234 = 4 sig figs
Number 2 1. 0506 =
Number 2 1. 0506 = 5 sig figs
Number 3 320 =
Number 3 320 = 2 sig figs
Number 4 • Write in scientific notation 450
Number 4 • Write in scientific notation 450 = 4.50 * 102
Number 5 Write in scientific notation 0.00457 =
Number 5 Write in scientific notation 0.00457 = 4.57 * 10-3
Number 6 Write in scientific notation 4569
Number 6 Write in scientific notation 4569 = 4.569 * 103
