set R = multMagma(# REAL ,multreal #);
( multMagma(# REAL ,multreal #) is unital & multMagma(# REAL ,multreal #) is commutative & multMagma(# REAL ,multreal #) is associative )
proof end;
hence multMagma(# REAL ,multreal #) is non empty strict unital associative commutative multMagma ; :: thesis: verum
