Preguntas frecuentes
Why do we mark a dot when borrowing?
When the ones digit is too small, you borrow 1 ten from the tens column. The dot reminds you that the tens digit is now 1 less, the most common place children slip.
Why does the second row of 2-digit multiplication move one place left?
You are multiplying by tens, so the answer is a number of tens and starts under the tens column.
Where do I write the quotient in long division?
Above the digit you have divided up to. If the part you are dividing is smaller than the divisor, write a 0 there. Each remainder must be less than the divisor.
