"And" is an undetermined function here as one could ask "What is the product of 13 and 34?" (indicating multiplication), or "What is the difference of 13 and 34?" (indicating subtraction).Since "plus" is specified and "and" is not, we can assume that "and" is not addition, or it would probably be specified as "plus" as well. We will assume that multiplication is the desired function:13*34+7*13 would be better written to clarify order of operations as(13*34)+(7*13), then reduced as442+91, and solved to533
The factors of 34 are 1, 2, 17, 34 To get to 13 you could use 13 ones or 6 twos and 1 one or some other combination of ones and twos.
