    Make sure your answers work by doing the opposite procedure of what your problem calls for, including the answer you got the first time around. In other words, you would use the opposite of this addition problem—subtraction (减法)—to determine whether your answer is the correct one.

    Plug in（代入）

    {#blank#}5{#/blank#}

If everything looks okay, do the problem again and compare the result of the second try to what you've got on the first try.

A. Do the opposite.
