Evaluate [ (30 + 6) - 32] : 9.2

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 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 H}}|G:H|={/frac }

division

divided by

over

everywhere

A : B means the division of A with B (dividing A by B) 10 : 2 = 5
