Continued 7 Drag the hide va ar iable name block from the e Data category c and add it to the bottom of the code stack. Change n the value to sum if needed. This block tells Scratch not to display the sum variable on the stage while the program is running. u 8 Applying what you y have learned, add code to set the variable sum equal to the total of the value of firstNumber m plus the value of secondNumber.b 9 Applying what you y have learned, add code to ask k the user “What is the sum of these two numbers?” and wait for the user input. Remember, the user input is stored in the answer variable. 0 Applying what you y have learned, add the if then n else block to the code stack, and code the expres ss ion IF answer equals sum. This s condition tests if the user’s answer is correct. - In the first section o of the if then else block, add the h code to say to the user “That is correct!” This is the code that will be executed if the condi it ion is true. = In the second se ec tion of the if then else block, add d the code that will be executed if the condition is false, as shown. Join the statement “S So rry…the correct answer is ” with the value of the vari ia ble sum. when clicked set to firstNumber pick random to 10 1 set to secondNumber pick random to 10 1 hide variable sum ask What is the sum of these two numbers? and wait set to sum + firstNumber secondNumber else if then answer = sum say That is correct! say sum . join join Sorry...the correct answer is Goodheart-Willcox Publisher q Click the Green Flag button to run the program. Run it several times, and test for correct and incorrect answers. n w Save the project t as HOE05-03D in your working fo ol der. Try It! Create a project for testing user input. The user m mu st enter a whole number from 1 to 5. e If the input is within n this range, report to the user tha at the entry was valid. If the input is not correct, report t to the user “Error in entry. Not a number from 1 to 5.” What code will you use to check k if the entry is a whole number? ?
