-13 + 34 = 21
34
It is -34 + v.
34 + 61 - 64 + 18 = 13
It is -34 + v.
"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
2 + 11= 13 13 +7 = 20 20 + 14 =34 so: 2 + 11 + 7 +14 = 34
It's Fibonacci's
24+24+34+34 = 116
78 + 34 is 112, which is an integer, not a fraction.
That's the beginning of the Fibonacci series.
