To compute the strides of the strided layout, the residues of the above operation are used to scale the strides of `A`. For instance, the last example `(3,6,2,8):(w,x,y,z) / 72` with strides `(w,x,y,z)` produces `(3*w,6*x,2*x,2*z)` as the strides of the strided layout.
As you may have noticed, we can only divide shapes by certain values and get a sensible result. This is called the **stride divisibility condition** and is statically checked in CuTe when possible.
2. Keep the first `s` elements of the newly strided `A` so that the result has a compatible shape with `B`. This can be computed by "modding out" the first `s` elements from the shape of `A` starting from the left.

#### Example 1 -- Worked Example of Calculating a Composition
We provide a more complex example of composition, where both operand layouts are multi-modal to illustrate the concepts introduced above.
