PEMDAS is the order of operations which explains how problems are to be solved.
The P stands for parentheses, ( ), ; parentheses are to be performed first if any.
The E stands for exponents, n^n, (being raised to a certain power) is then performed.
The M stands for multiplication, * or x, and this is then performed.
The D stands for division, /, and this is then performed.
Multiplication and division are performed in the order read (left to right); what comes first is solved first as long as it is after parentheses and exponents.
The A stands for addition, +; which follows.
The S stands for subtraction, -, then performed.
The same rules for multiplication and division apply for addition and subtraction. Although addition is listed first, problems are solved in the order they are read as long as PEMDAS is followed.
Therefore, -9 * -8 - 16 = 56.
Multiplication is read first in -9 * -8 to equal 72.
This is then subtracted by 16 to get 56.

that is the same as 2 x 72 dived by 9 2 x 72/9 = 2 x 8 = 16
What is 9 is to 2 as x is to 16?
9:2 :: x:16 We note that 16 = 2 x 8 So to bring to equivalence . the 'x' is 9 X 8 = 72 Hence 9:2 :: 72:16 Note the use of colons for 'is to', and 'as'.
Are the inequalities x -8 and -x 8 equivalent?
-16

(-9 x -8) + (-16) = (72) -16 = 56
What is 8 over 15 divided by 9 over 10?
(8/15) / (9/10) = (8/15) x (10/9) = (8/3) x (2/9) = 16/27

(9/16) / (5/8) = (9/16) x (8/5) = 72/80 = 9/10 = 0.9
16 over 21 divided by 8 over 9?
To divide by a fraction, multiply by its reciprocal. In this instance, 16/21 / 8/9 is equal to 16/21 x 9/8 = 0.857142 recurring (that is, 0.857142857142...)
9 is to 2 as x is to 16?
9/2 = x/16We can see that 8(2) = 16, so multiply by 8 to the numerator and denominator, giving:72/16 = x/16Getting x = 72.You can also use cross multiplication:144 = 2xDivide by 2:72 = x.
