As the term implies, significant figures are figures or numbers that are significant to the answer
Take for example:
a. original number is 12345, anwer in 3 significant figures would be 12300. From the left only the 1st 3 figures are counted. Rounding off not affecting the answer.
b. Similarly, if we have original number as12355, answer is 12400. First 3 figures but need to round off using the 4th.
c. 1.2345 would give 1.23
d. 1.2355 would give 1.24
e. 1.2955 would give 1.30 round off but must show 3 digits in answer.
f. 1.1 would give 1.10
g. 1.9955 would give 2.00
Hope this helps.
