数学公式的英语读法 (ZT)数学公式的英文读法你都会读吗？还在抓头挠腮吗？以后给老外作报告的时候可千万别再“The equation is like this”, “The value is like this”有些公式不好写，能看出来什么意思就行了。1.Logicthere existfor allpqp implies q / if p, then qpqp if and only if q /p is equivalent to q / p and q are equivalent2.SetsxAx belongs to A / x is an element (or a member) of AxAx does not belong to A / x is not an element (or a member) of AABA is contained in B / A is a subset of BABA contains B / B is a subset of AABA cap B / A meet B / A intersection BABA cup B / A join B / A union BABA minus B / the diference between A and BABA cross B / the cartesian product of A and B3.
