建构式数学，是伟大的成语大师杜证剩担任中华民国教育部部长任内罄竹难书的政绩之一，是一种为了消灭加强下一代计算能力，好让黑预算过关的阴谋政策。学成之后有相当大机会进入婶计部与主祭处工作，成为脑残的公务员。

593=500+90+3

638=600+30+8

500+600=1100=1000+100

90+30=120=100+20

3+8=11=10+1

593+638=1000+(100+100)+(20+10)+1=1231

• 其余减乘除都用此方式，这种将数字切开自小数点第四位的算法是非常的明智！！！！

据说，此数学方式原本是给贱人与狗学习用的，故又称贱狗式数学。且注意必需再学正统的九九表，否则会遭致脑残的命运。且根据研究发现，此数学运算方式会让人类大脑神经衰弱而导致健忘的症状，所以有部分专家称其为健忘式数学。
