Answer:
you would want to do 30 +6 first which would be 36 than subtract 32 from that which would leave you to have 4
and this is the definition for : symbol and it should be easy to finish your equation
:\!\,
such that
such that;
so that
everywhere
: means "such that", and is used in proofs and the set-builder notation (described below). ∃ n ∈ ℕ: n is even.
field extension

over
field theory
K : F means the field K extends the field F.
This may also be written as K ≥ F. ℝ : ℚ
inner product of matrices
inner product of
linear algebra
A : B means the Frobenius inner product of the matrices A and B.
The general inner product is denoted by ⟨u, v⟩, ⟨u | v⟩ or (u | v), as described below. For spatial vectors, the dot product notation, x·y is common. See also bra–ket notation. {\displaystyle A:B=\sum _{i,j}A_{ij}B_{ij}}A:B=\sum _{i,j}A_{ij}B_{ij}
index of a subgroup
index of subgroup
group theory
The index of a subgroup H in a group G is the "relative size" of H in G: equivalently, the number of "copies" (cosets) of H that fill up G {\displaystyle |G:H|={\frac }}|G:H|={\frac G}
division
divided by
over
everywhere
A : B means the division of A with B (dividing A by B) 10 : 2 = 5
