Significant figures are essential to science because they make the answer more precise when the tools require us to use estimation. Significant figures are the digits that contribute to the value of a number. Throughout the lab we were given instructions to measure different objects using different tools with the objective of figuring out how the amount significant figures affect the accuracy of the measurement. Firstly‚ it is important to know and understand significant figures because they make

INTRODUCTION The Babylonians used a sexagesimal (base 60) numeral system to make astronomical calculations‚ from which the use of 60 seconds in a minute and 60 minutes in an hour is derived. I will research how the Babylonians used this system to measure time. I have chosen the topic Babylonian time system as it relates history and math. I find it fascinating how in the past‚ people had to come up with elaborate theories and intricate systems from scratch‚ as compared to how modern day mathematicians

1. If 5 times the value of a number is increased by 3‚ the result is 28. What is the number? 5x+3=28 5x=25 x=5 The answer is 5 2. If 4 times the reciprocal of a number is 3 more than 5/2 times the reciprocal of that number‚ find the number. 4*(1/x)=(5/2)*(1/x)+3 4/x=(5/2x)+3 (8/2x)=(5/2x)+3 (8/2x)-(5/2x)=3 (3/2x)=3 x=1/2 The answer would be x=1/2 3.

The sequence of exercises through which the child is introduced to the group operations with the Golden Beads Math operations include addition‚ multiplication‚ subtraction‚ and division. All these operations require full understanding of quantities on a concrete level before moving to the abstract level of performing these operations mentally. So the first exercise introduced to the child to prepare him for these operations; is the “Number Rods”. The ten number rods are graduated in length from

You know that a number is written in scientific notation when there is a decimal number with one digit to the left of the decimal. For example let us take the number 53‚000‚000. In scientific notation it would be written as 5.3*10^7 156. Explain how to convert from scientific to decimal notation and give an example. This is the opposite of
