Question on simple fraction evaluation

[DougM52]

Using wxMaxima 18.02.0

Not sure why (24 - 3) * (4 + 28) / 14 evaluates to (3* (32))/2 but 21 * 32 / 14 evaluates to 48. The two is tests I would think would be true. How do I get the (3* (32))/2 to evaluate to 48 as does 21 * 32 / 14 ?

(%i104) /*
(b)
(24 - 3) * (4 + 28) / 14;
(24 - 3)/14 * (4 + 28)
(3 / 2) * 32
3*16;
48;
/
(24 - 3) * (4 + 28) / 14;
21 * 32 / 14;
is ((24 - 3) * (4 + 28) / 14 = 48);
is (21 * 32 / 14 = 48);
(%o101) (3 (32))/2
(%o102) 48
(%o103) false
(%o104) true

It appears to work if I trim spaces out of the expressions.

(%i9) /*
(b)
(24-3)(4+28)/14;
(24-3)/14(4+28)
(3/2)32
316;
48;
/
is ((24-3)(4+28)/14=48);
is (21*32/14=48);
(%o8) true
(%o9) true

Then you use an old wxMaxima Version and have accidentally used nonbreakable spaces.
