According to the order of operations, what should
be performed first to simplify the expression.
10 + 18 + 6 + 3×2

You should follow GEMDAS or PEMDAS

answer is 40

Step-by-step explanation:

G or P stands for grouping devices or parentheses

E stands for exponents (not needed)

M and D stand for multiplication or Division (use which ever comes first left to right)

A and S stand for addition and subtraction (use which ever comes first)

sooo...

1) 3x2=6  now 10+18+6+6

2) 10+18=28 now 28+6+6

3) 6+6=12  now 28+12

4) 28+12=40 answer is 40

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3
