this is a calculator we use it to calculate with numbers.
    For example , one plus one is two, two and three equals five, ten minus six is four, three times four equals 12, then how much is 12 divided by four ? it’s three ! Easy-peasy right ?
    Now tell me, how much is half times three quarters？
    这是一个计算器，我们用它来计算数字。
    例如，一加一等于二，二加三等于五，十减六等于四，三乘四等于12，那么12除以四等于多少？ 是3！ 轻轻松松对吧？
    现在告诉我，二分之一乘以四分之三等于多少？
