9Multiple formulas can be combined by wrapping them:

11\startbuffer
12
13\fakewords{20}{30}
14
15\startformula
16    a + b = c
17\stopformula

22    \startformula
23        a + b = c
24    \stopformula
25    \startformula
26        d - e = f
27    \stopformula

33    \startformula
34        \frac{\frac{x}{y}}{b} = c
35    \stopformula
36    \startformula
37        d - e = f

46When we bump the space around formulas to \type {big} we get this:
47
48\start
49    \setupformulas[spacebefore=big,spaceafter=big]
50    \appendtoks\showmakeup[reset]\to\everymath
51    \showboxes
52    \getbuffer
53\stop
54
55The formulas get aligned on the baselline which in turn relates to the
56math axis of the formula.
