Week 1 Lesson 1: Palimages A palimage of a counting number is the number that has the same digits as the given number but in reverse order. For example, 659 and 956 are palimages; so are 1327 and 7231. Now add 354 and it palimage. Call this sum X. Add X and its palimage. Call this sum Y. Add Y and its palimage. Call this sum Z. What is the value of Z? Solve this problem and then remove the rectangle to check your answer. 1 354 + 453 807 X= 807 1 807 +708 1,515 Y= 1,515 1,515 5,151 6,666 Z= 6,666 Go to the next slide and solve the problem. Add 567 and it palimage. Call this sum X. Add X and its palimage. Call this sum Y. Add Y and its palimage. Call this sum Z. What is the value of Z? Check your answer by removing the blue rectangle. Go to the next slide and solve the problem. Multiply 24 and it palimage. Call this product X. What is the value of X? Solve the problem and check your answer by removing the blue rectangle. 1 24 X 42 42 x 20 840 42 x 4 168 840 +168 1,008 X= 1,008
