First when solving, we have to use PEMDAS. What is PEMDAS, you ask? Well, it's an acronym for the order we solve a problem by. (The order of oporations)
P- Parentheses
E- Exponents
M- Multiplication
D- Division
A- Addition
S- Subtraction
Since parentheses is first, that means if there's parentheses in the problem, that's the first thing you'll solve.After you've solved whatever was in parentheses, (or if there were any, if there wasn't, you'd skip to this step), you'll solve any exponents next in the problem.
After you've solved the exponents, (or if there were any, if there wasn't, you'd skip to this step), you'll now solve any multiplication in the problem. HOWEVER, with multiplication, division, addition, and subtraction, you'll solve whatever is FIRST in the problem.
For example, 15 divided by 3 times 2 minus 6 plus 5.^Since division is first in the problem, you'd divide 15 divided by 3, which is 5, then continue the rest of the problem.
Let's solve this problem using the order of operations of PEMDAS;2+2-3*6-8+10/100-23+2.4^Multiplication is first instead of division, so we'll multiply 3 times 6 first, and 3 times 6 is 18. Now there's some division in this problem, and we'll do that next.10 divided by 100 = 0.1.
Now let's rewrite this equation.2 + 2 - 18 - 8 + 0.1 - 23 + 2.4Since addition is now first in the equation, we'll add 2 + 2, which is 4, and since subtraction is next, we'll subtract 4 minus 18 which is -14, and since the subtraction is still continuing, we'll subtract -14 minus 8, which is -22, and now that addition is next we'll add -22 + 0.1, which is -21.9, and since subtraction is next we'll subtract -21.9 minus 23, which is -44.9, and since addition is next we'll add -44.9 + 2.4, which is -42.5.
So, the correct answer you are looking for is: -42.5.
Good luck with your studies, I hope this helps~!
