New Answerint("3" + "4") isn't necessarily the same as int("3") + int("4"), but rather the same as the following code (but without the extra variable): x = "3" + "4" # x is now "34" int(x) # Converts x to a string With the int function, it will essentially evaluate the expression within the brackets before continuing with the type-conversion, which is why the output is 34 rather than 7

Because the plus operator has three implementation. Arithmetic addition for integer, arithmetic addition for floating number and concantention for string. When 3 is enclosed with quotation mark, it is a string, so the plus operator is string concantention here, just like "a" + "b" = "c"

Int("3" +"4") will never be equal to 7. Because 3 and 4 are enclosed in a quote, which makes them a type string. Int (3+4) != int("3" + "4"). The +sign just join the two strings together. Like x = ( "james" + "bond" ) So, x = jamesbond

In short, You are using quotations so you're not adding, you're putting together. If: "A"+"b"= Ab Then "3"+"4"+= 34
