How to do the math sloppy problems in the second book of the third grade?
Look at it on a case-by-case basis
Division without remainder: Divisor÷ divisor = quotient
Look at the wrong remainder, first find the divisor, and then find the correct quotient;
Division with remainder: See the wrong divisor, the remainder is the same, want to calculate how much the difference between the two divisors, and then use the difference number to divide the quotient, first find out the divisor.
