Find the elementary arithmetic problem of the first grade mathematics in the four new curriculum standards? It's hard.
(1).543 times 38 divided by 2 plus 45=(2).500 times 6+5000-8000 divided by 2-4000=(3). (negative 3) times 5/6 times (negative 9/5) times (negative quarter) = (4). -8 (-6)=(6).(- 1.5)*3+2*3+ 1.7*4+(-2.3)*2=(8).26*(-4 1)+(-35)* (- 17)=(9).-5. 13+4.62+(-8.47)-(-2.3)=( 10) .1.252 ÷ (-44)-(-356) ÷ (-0.196) = (11). (-7) * (-3) * I really can't think of it in my head, I can only think of it, but I suggest you give it to me.
