163 * 80 − 153 * 47 − 153 * 33 compute in the most rational way BRAINLIEST IF CORRECT

820

Step-by-step explanation:

Some people may get confused and just calculate this question from left to right, but I was taught to use this formula:

Brackets

Exponents

Division

Multiplication

Addition

Subtraction

So lets multiply first,

163 × 80 = 13,040

153 × 47 = 7,191

153 × 33 = 5,049

Next, we subtract:

13,040 - 7,191 - 5,049 = 820

Have a good day :)

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
