The following is my analysis of the test paper.

Question:
Error: How much did the clothes cost? 120 ×30=3600 (yuan)
Correct: How much is a coat and trousers? 3600+8600= 12200 (yuan)
Reason: I lost 3 points because "asking questions according to the completed grades" was misunderstood.
Seven, solve practical problems.
(4) The average length of Xiao Ming's step is 6 1 cm. He walked 500 steps from home to the post office. How far is his home from the post office?
Error: 48× 500 = 30,500 (m) Answer: The home is 30500m away from the post office.
Correct: 6 1×500=30500(cm) A: The home is 30500cm away from the post office.
Reason: I wrote the wrong unit because I didn't read the questions carefully. Lost 1 point.
Summary: Both the teacher and mother told me to do the problem carefully, read it clearly, understand it and read it three times. How can I forget them? I will remember them in the future! ! !
Mom's words: Son, this time is really not ideal. If you are serious, you can't lose 7 points. Can analyze their own gains and losses, know their own shortcomings, learn lessons, there will be gains! ! !
