If the signs at the front of the numbers are different then the one with the negative sign is smaller. So the question can be simplified to ordering two numbers that have the same sign. Suppose they are both positive numbers.
If one of them has a smaller exponent (power of 10) than the other, then that number is smaller.
That then leaves two positive numbers with the same exponent. So the only difference is in the mantissa (or the bit before the power of 10). Since the powers of 10 are the same in both cases, the smaller mantissa gives the smaller number.
Going back to the case where both numbers are negative: their ordering is the same as for negative integers, for example. The bigger absolute value gives the smaller negative number.

Which of the following correctly expresses the number below in scientific notation of 0.0000752?
In order to write a number in scientific form, you first need to divide it by a power of 10 such that the greatest place value is the units. In this case, you can divide by 0.00001 to get 7.52. The next step is to represent this power of 10 next to the number as a multiplication. In this case we used 0.00001, which is 10-5 Thus 0.0000752 in scientific notation is 7.52x10-5
What is 2010000 in scientific notation?
When we convert a long number to scientific notation we need to identify the significant digits.In 2010000 we have only three significant digits (201) as the remaining zeros wont change the value of the number once we place it in scientific notation.The rules of SN (Scientific Notation) state that our number must be between 1-9 so in order to make it between 1-9 we have to move the decimal place to the left.With moving decimals to the left the exponent that will be placed by x 10N will result in a positive number. When we move to the right we will find a negative number.2010000 x 100201000.0 x 10120100.00 x 1022010.000 x 103201.0000 x 10420.10000 x 1052.01 x 106So 2010000 in scientific notation is 2.01 x 106And in Computerese...This can also be expressed as 2.01E6
What are two numbers written in a specific order and enclosed in parentheses called?
That is an ordered number pair. It is normally used to specify a location on a graph, the numbers indicating the values of x and y, in that order.
What are inequalities?
An inequality is actually an equation. It is solved just like an equation, except it has no exact answer. Instead many numbers will satisify the inequality.For this reason the answers on a inequality are plotted on a number line.The answers are also written as a set of numbers.In mathematics, an inequality is a statement about the relative size or order of two objects, or about whether they are the same or not (See also: equality). *The notation a < b means that a is less than b. *The notation a > b means that a is greater than b. ...
What is it called when you arrange numbers from greatest to least?
This is known as arranging the numbers in ascending order.
