## 17-2(5-3)=

i simply need the break down of this math equation

To help you with this, recall the PEMDAS mnemonic PLEASE EXCUSE MY DEAR AUNT SALLY. In other words 1. Evaluate the contents inside PARENTHESES using order of operations. 2. Evaluate all EXPONENTS. 3. Evaluate all MULTIPLICATIONS and DIVISIONS going from left to right. 4. Evaluate all ADDITIONS and SUBTRACTIONS going from left to right. Example: (100-2*7^2+1)^3*7/9*3^2+4-2^5. Evaluating inside contents of parentheses gives 100-2*7^2+1 = 100-2*49+1 = 100-98+1 = 3 Now you can do the rest: (100-2*7^2+1)^3*7/9*3^2+4-2^5 = 3^3*7/9*3^2+4-2^5 = 27*7/9*3+4-32 = 63+4-32 = 35. Now try it on your equation.

There is an error in my last step (ignored the squaring accidently). it should be 3^3*7/9*3^2+4-2^5 = 27*7/9*9+4-32 = 189+4-32 = 161

So, here is the Order of Operations you would use to break down the problem.

1. Parenthesis

2. Multiplication and Division

(Note: for future problems, if you have two of the same sign, you just work left to right, as if you were reading a sentence.)

So: 17-2(5-3)

First, do what is in the Parenthesis: 5-3=2

Now you have 17-2 x 2 (when the numbers are bumped up against the parenthesis like that, it always means to multiply), so you do the multiplication next: 17-4

You have to do the parentheses first (order of operations) then the other part, i.e. 17-2.

5-3=2 so now it will read 17-2-2= 13
