To multiply multi-digit numbers, split one number into tens and ones, find the partial products and add them: 347 × 26 = 347 × 20 + 347 × 6. For decimals, multiply as if there were no points, then count the decimal places in both factors and give the product the same number of places. To divide, estimate with compatible numbers, divide place by place, and write the remainder or continue with zeros. When the divisor is a decimal, multiply both numbers by 10 or 100 first. Always check: multiply the quotient by the divisor and add the remainder.
