1、六年级定义新运算专题简析：定义新运算是指运用某种特殊符号来表示特定的意义，从而解答某些特殊算式的一种运算。解答定义新运算，关键是要正确地理解新定义的算式含义，然后严格按照新定义的计算程序，将数值代入，转化为常规的四则运算算式进行计算。定义新运算是一种人为的、临时性的运算形式，它使用的是一些特殊的运算符号，如：*、等，这是与四则运算中的“、”不同的。新定义的算式中有括号的，要先算括号里面的。但它在没有转化前，是不适合于各种运算定律的例题 1。假设 a*b=(a+b)+(a-b),求 13*5 和 13*（5*4）。13*5=（13+5）+（13-5）=18+8=26 5*4=（5+4）+（5-4
2、）=10 13*（5*4）=13*10=（13+10）+（13-10）=26 练习 1 1.将新运算“*”定义为：a*b=(a+b)(a-b).求 27*9。2.设 a*b=a2+2b，那么求 10*6 和 5*（2*8）。3.设 a*b=3a12b，求（25*12）*（10*5）。例题 2。设 p、q 是两个数，规定：pq=4q-(p+q)2。求 3(46).3(4 6).3【46（4+6）2】319 419（3+19）2 7611 65 练习 21设 p、q 是两个数，规定pq4q（p+q）2，求 5（64）。2设 p、q 是两个数，规定pqp2+（pq）2。求 30（53）。3设 M、N
3、是两个数，规定M*N MN+NM，求 10*2014。例题 3。如果 1*5=1+11+111+1111+11111，2*4=2+22+222+2222，3*3=3+33+333，4*2=4+44。那么 7*4=？，210*2=？7*4=7+77+777+7777=8638 210*2=210+210210=210420 练习 3 1如果 1*5=1+11+111+1111+11111，2*4=2+22+222+2222，3*3=3+33+333，.那么，4*4=？，18*3=？2规定 a*b=a+aa+aaa+aaa+aaaa.a,那么 8*5=？（b-1）个 a 3如果 2*1=12，3*
4、2=133，4*3=1444，那么（6*3）（2*6）=？。文档编码:CO1U7V2G3Z2 HQ2C3H6S2G8 ZM1N1N2S2T4文档编码:CO1U7V2G3Z2 HQ2C3H6S2G8 ZM1N1N2S2T4文档编码:CO1U7V2G3Z2 HQ2C3H6S2G8 ZM1N1N2S2T4文档编码:CO1U7V2G3Z2 HQ2C3H6S2G8 ZM1N1N2S2T4文档编码:CO1U7V2G3Z2 HQ2C3H6S2G8 ZM1N1N2S2T4文档编码:CO1U7V2G3Z2 HQ2C3H6S2G8 ZM1N1N2S2T4文档编码:CO1U7V2G3Z2 HQ2C3H6S2G8 Z
