To check a multiplication calculation:

Question

BlackTom AI · Accepted Answer

When checking a multiplication calculation, you want a step that verifies the relationship between the factors and the product without introducing new operations that don’t relate to the original multiplication.
Option 1: 'divide the answer by the multiplier' — This makes sense because if you multiply two numbers (the multiplicand and the multiplier) to get a product, dividing the product by one of the factors should return the other factor. It directly tests the consistency of the result with the original numbers.
Option 2: 'multiply the answer by the divisor' — This would not be a standard check for a multiplication; it introduces an extra multiplication that does not test the original equality. It would only be meaningful in a different context (e.g., scaling), but not for verifying a given product against its factors.
Option 3: 'subtract the multiplied figures from the total' — Subtracting the product from a total is not a method used to verify a multiplication; it assumes a total that is already related in a specific way, which is not generally how you confirm a correct product. It can lead to confusion rather than validation.
Option 4: 'divide the multiplier by the answer' — Dividing the multiplier by the product is not a valid check of a multiplication; it reverses the expected operation and does not reliably recover the other factor, especially since the product is typically larger than the factors and may introduce fractions or undefined results if zeros are involved.
In summary, only the operation described in Option 1 aligns with the mathematical principle that the product divided by one factor yields the other factor, providing a straightforward cross-check of a multiplication result.
