So, again, the quotient can only have as many significant digits as the least amount of So if the dividend has 3 significant digits and the divisor has 2 significantĭigits, for example, the quotient of the division operation can only have 2 significant digits in it. When dividing significant digits, the amount of significant figures in the final product is determined by the number of significant digits in the dividend and the divisor.Ĭan only have as many significant digits as the dividend or the divisor with the least amount of significant digits. So, for example, in the division operation, 8/2= 4, 8 is the dividend, 2 is the divisor, and 4 is the And the quotient is the resultant answer from the division operation. The divisor is the number that isĭividing a number. The dividend is the number being divided. Just to understand terminology, in a division operation, there is a dividend, a divisor, and quotient. This is why using the proper amount of significant digits is so important. The recorded value cannot have more significant digits than the measuring tool allows. And how we make the recorded value honest is byĬontrolling the number of digits, or significant figures, used to report the measurement. So that the resulant value does not appear to be more accurate than the equipment used to make the measurement allows. It is important to be honest when making a measurement, Thus, we can have an extra significant digit, because the ruler is more detailed and allows for more If we now change the rulerĪnd get one which measures millimeters, we can measure to one-thousandth of a meter. For example, if we have a ruler that only measures centimeters, we can measure to one-hundredth of a meter. Record much more in detail than other measuring tools. Different measurement tools can record measurements of differing accuracy. Significant digits are used extensively during measurements. Significant digits in a number are those values which can be known withĬertainty or a high degree of confidence, while insignificant digits are those which we do not trust as very accurate. Significant figures, or digits, are the values in a number that can be counted on to be accurate.
