How to learn midpoint and significant figures

Every start has an end. Each start and end goes along a journey where it happens to complete its golden jubilee or fifty percent of the very journey towards ending. That point of 50/50 partition is known as Midpoint.
When you talk about geometry, at every inch we need to learn about the lines, symmetry, and angles of tangents. Each line divides itself into half or two parts and the point where both the starting and ending points are equidistant from the center is called the midpoint of that line.
The centroid or the point with equal distance for both the initial and final point is the Midpoint
=(x1 + x2/2 , y1 + y2/2)
Derive the Midpoint formula
The midpoint is the halfway of any line and here in the formula the expression for x coordinate is x1+x2/2 and similarly the expression for the y-coordinate is y1+y2/2
M =(x1 + x2/2 , y1 + y2/2)
like if we have two points with midway points on the geometric graph
(x1 + x2 /2 , y1 + y2 /2)
=(8 + -4 /2 , -11 + 5/2)
= (4/2 , -6/2)
M = (2 , -3)
To find the midpoint is no big deal, in fact, someone can forget the formula but can easily derive the midpoint of the two lines as this goes along with the very basic skills. You can also use an online midpoint calculator.
Significant figures
The significant figures are the precision or significant digits of any measurement or the number written in positional notation are the digits that carry reasonable contribution to its measurement resolution. These digits include all except
The leading zeros. For example, 012 has two significant figures i.e., 1 and 3.
Trailing zeros when they are the placeholders to determine the scale of the numbers.
Spurious digits were introduced, i.e., that the final calculations would be of greater precision than that of the original data.
From all the significant figures of any number, the most significant one is considered on the position it holds, with the highest exponent values (standing at the left-most side in the basic decimal notation), and the least or the less significant figure is the position with the lowest exponent value i.e., the right-most in the decimal notations).
For example, in the numbers '234' the '2' is the most significant figure as it counts hundreds (100) or thousands and 4 is considered as the least significant figure as it counts as hundred (100) and 4 is the right-most figure the least significant one.
Significance arithmetic is a set of approximate rules that is used to roughly maintain the significance throughout a computation. The more sophisticated scientific rules are known as the Propagation of uncertainty (the uncertain values of the uncertain measurements).
The numbers are often puzzled around to avoid reporting
non-significant figures. For example, it would create some precisions to express some measurements as 12.34567kg a seven-digits figure, if the measuring scale only measures the nearest gram and show a reading of something around 12.345 kg a figure with five significant digits. The numbers can also be rounded just to make it simple rather than to find or to obtain any given precision of measurement, as an example, just to make them clear and fast to pronounce in the news broadcast.
Rules of Significant figures
There are some rules given to determine the significant figures, specifically, the rules applied for identifying the significant figures when writing or interpreting numbers are shown as follows
All the non-zero digits are considered a significant figure. For example, 98 has two significant figures (9 and 8), while 1234.5 has five significant figures (1, 2, 3, 4, and 5).
Zeros appearing anywhere between any of two non-zero digits are said to be a significant digit or figure like 102.1204 has seven significant figures: 1, 0, 2, 1, 2, 0, and 4.
Zeros to the extreme left of the significant figures are not considered significant. For example, 0.00046 has two significant figures i.e., 4, and 6.
