Sorry if I went into too much detail, I don't know what you do/don't know
Firstly, inside the brackets must be done:
12.077*1.2/6.3-2.01
After this, try to visualise the problem with the divisions as a fraction:
\(12.077\times\left ( \frac{1.2}{6.3} \right )-2.01\)
(this makes it easier to see that divisions have priority)
Next, you can multiply the 12.077 with the 1.2
The BIDMAS rule is to divide first but that is due to mistakes that can occur when the divisions are not represented as fractions e.g.
{1/2*3} If you did multiplication here first, you would get {2*3=6}, therefore [1/6]. You should do division here first {1/2=0.5}, then {0.5*3=1.5}
If you visualise this in terms of the division being a fraction, it makes it a lot easier to see that multiplying the 2 and 3 would be multiplying the denominator 2 by 3. Otherwise, if you know how to multiply fractions, you will see {\(\frac{1}{2}\times3\)} that the 1 (the numerator) is multiplied by 3 instead.
Continuing with the question:
\(\frac{14.484}{6.3}-2.01\)
Next you have to divide 14.484 by 6.3, which will give a number with a lot of decimal places, so I will round down
\(2.3-2.01=0.29\)
