Calling the Functions with Arguments

i am not understanding how to call the function

Your code so far

// Example
function ourFunctionWithArgs(a, b) {
  console.log(a - b);
ourFunctionWithArgs(10, 5); // Outputs 5

// Only change code below this line.
function functionWithArgs(a,b) {
  console.log(a +b );
call functionWithArgs(1,2)
