Are there programming languages with implicit multiplication?

Question

Is there a programming language in which any of the following:

a numeric literal next to a variable 3x,-0.5y
numeric literal or numeric variable next to the expression in parentheses a(b+c+d) 2(x-y)
two adjacent parenthesized expressions (1+x)(1-x) (4a-5b)(1+4c)

interpreted as multiplication?

I see syntax problems that this can cause, but I'm curious if any language went ahead and did it anyway.

TI-BASIC does this in certain circumstances. I believe that certain CAS-oriented pagans also do.

IIRC, Fortress has a "matching operator", which for numeric types is defined as multiplication.
