This is not a question, this is for who-ever needs it. Order of Operations

Remember the order of operations starts with the parentheses and moves down the list.
1. Parentheses
2. Exponents
3. Multiplication/Division
4. Addition/Subtraction

Example 1

Evaluate the expression 62 + 35 ÷ 3.

Steps to Simplify

Calculations

The first step to evaluating this expression would be to simplify the exponents.

36 + 243 ÷ 3

62 = 6 × 6 = 36
and
35 = 3 × 3 × 3 × 3 × 3 = 243

The next step is to evaluate any multiplication and/or division from left to right.

36 + 81

243 ÷ 3 = 81

Last, complete any addition and/or subtraction from left to right.

117

36 + 81 = 117

Therefore, 62 + 35 ÷ 3 = 117.

Example 2

Evaluate the expression 5 × (2/3)3 + 70 − (2×4)2.

Steps to Simplify

Calculations

The first step would be to simplify the expression in the parentheses.

5 × (2/3)3 + 70 − 82

2 × 4 = 8

Now you simplify the exponents.

5 × 8/27 + 70 − 64

(2/3)3 = 2/3 × 2/3 × 2/3 = 8/27

82 = 8 × 8 = 64

Next, complete all multiplication and/or division from left to right.

1 13/27 + 70 − 64

5/1 × 8/27 = 40/27 = 1 13/27

Last, complete all addition and/or subtraction from left to right.

71 13/27 − 64

7 13/27

1 13/27 + 70 = 71 13/27

71 13/27 − 64 = 7 13/27

Use the spider tool located on page 1 of this activity to draw a 12-pointed star for the new logo. (hint: if the spider rotates 360 degrees -- or 720 degrees or 1080 degrees -- she will be facing in the same direction in which she started. when the spider is done drawing, you want her to be facing in the same direction in which she started. she'll be making 12 rotations, all the same size, so each rotation must be some multiple of 360/12 = 30 degrees.) urgently. been stuck on this problem for around 45 minutes now.! it should be easy if you're smart enough
