They're commonly used in real-world situations like measuring temperatures below freezing. Understanding negative numbers helps us grasp a broader range of mathematical concepts. Inductive reasoning starts from the bottom to the top (in this case, 1950 to 2020), and deductive reasoning goes from the top back to the bottom. We can only make a generalization about the future, but to make a prediction about history would use deductive reasoning since we know there was a decrease every year.

Dividing the exponent by 4 and having a remainder of 1 or 0 means the tens digit will be 0. Dividing the exponent by 4 and having a remainder of 2 or 3 means the tens digit will be 4. 1993 divided by 4 yields a remainder of 1. AboutTranscript. Significant figures are the number of digits in a value, often a measurement, that contribute to the degree of accuracy of the value. We start counting significant figures at the first non-zero digit. Calculate the number of significant figures for an assortment of numbers. Created by Sal Khan.

Start with ax^2 + bx + c = 0. Factor out a. a (x^2 + (b/a)x + c/a) = 0. Now we complete the square using the term (b/a)/2 or b/ (2a), adding and subtracting it to the one side so we don't …
