Thank You so much for making this easy to understand. I got a tutor and was More confused when I left than I was when I started. But could you please continue explaining how to multiply and divide with different significant numbers. Example 9.98 / 98.1735 and 697.1 • 2.410

@Allison0776 yes! watch my next video, significant figures 1.2. i have a whole series of sig fig videos, you can watch them in order and everything should make sense!

My textbook says that your example 56x28 would be correctly written as 1.6 x 10^3 which clearly shows two sig figs. It's a good approach, right?

[tdewitt451]

@TheIkitta if that already makes sense to you, go for it. i talk more about that approach in my video "scientific notation and significant zeros (1.8)."

Thank for the lesson

but accoring to my book 3.385 will be round into 3.38 i.e if the digit is Even before 5 then that even number will remain unchange, i.e 3.38 And if the digit is odd before 5 then it will be round into its next even number.
