Mathematical Rational Calculation in Seventh Grade

-2+(-8)-(-9)

15+(-1/4)-15-(-0.25) 8-2×3 3-(-0.25) -2-12-(-1/3-1/4+1/2) To write a solution, write a recursive equation calculation

(1) Original formula =(15-15)-(1/4-0.25)=0-0=0(2) Original formula=8-66+0.25=-58+0.25=-57.75(3) Original formula=-2-12-(-4-3+6)/12=-2-12-(-1/12)=-2-12+1/12=-167/12
