What is the answar 7 4 plus 3x0 plus 1?

Answer 1

4

There are no brackets or exponents, so you do multiplications and divisions first, from left to right.

7 - 4 + 3 * 0 + 1 = 7 - 4 + 0 + 1 = 7 - 4 + 1

Then you do additions and subtractions, from left to right.

7 - 4 + 1 = 3 + 1 = 4

Note that unless there are brackets indicating otherwise, terms are added to and subtracted from the total. It is not correct to add the 1 to the 4 making 5 and then subtract the 5 from the 7. That would amount to subtracting the 1 instead of adding it. The mnemonic BEDMAS is misleading in that is does not make it clear that divisions and multiplications are done with equal priority, and additions and subtractions with equal priority, I.e that all multiplications and divisions are applied to the product, and all additions and subtractions to the sum (except as indicated by brackets).
