Question
Chapter 2, Problem 2SC
Interpretation Introduction
Interpretation:
The direction for decimal point to move, to obtain the number in decimal notation, from its scientific notation, having a negative exponent, is to be predicted.
Concept introduction:
Decimal notation is a system where numbers, expressed in scientific notation are written in the form of large or small numbers containing many zeros.
Scientific notations are used to express a large number in a compact form.
Scientific notation consists of two parts, a decimal part (a number between 1 to 10) and an exponential part (10 raised to an exponent).

- CHEMISTRY 101 LECTURE NOTES Rules for Significant Figures in Mathematical Operations 1. For multiplication or division, the number of significant figures in the result is the same as that in the measurement with the smallest number of significant figures. We say this measurement is limiting because it limits the number of significant figures in the result. 2. For addition or subtraction, the limiting term is the one with the smallest number of decimal places. SAMPLE EXERCISE: Carry out the following mathematical operations, and give each result to the correct number of significant figures. a. (25.36 - 4.15) 2.317 b. (3.60 x 10) × (8.123) 4.3 c. 21 + 13.8 + 130.3 d. 116.8 - 0.33 e. (12.6 x 0.53) - 4.59 1.2.8 Accuracy and Precision In discussing measurements and significant figures it is useful to distinguish between accuracy and precision.
