Dear students: (70 minutes to complete the paper) Results:

Hello! In order to understand the learning situation of one semester and make faster progress in the future, I believe you can answer it easily and seriously. I wish you good results in the exam!

I. Calculation: 37%

1. Number directly filled in: 5%

34 - 12 =22 25÷26 =25/26 3 10 + 25 = 335 1 - 49 + 59 =

78 + 58 = 136 0.23 = 2 - 23 = 1 - 0.32 = 0.68

2. Use a simple method to calculate the following question: 5%

1 1 12 + 58 + 38 + 1 1 12 5 - 37 - 47 25 × 20 + 35 ×

= 1 1 12*2

3. Recursive equation calculation: 9%

56 - 14 + 13 2328 +( 13 14 + 27 ) 7–( 34 - 25 )

4. Solving equation: 6%

X+29 = 79 2 X- 16 = 56 35-X = 1-34

5. Formula calculation: 6%

①79 minus the sum of two 16; ② Subtract a number from the difference between 78 and 14 to get 25.

What is the difference? What's this number?

6. Calculate the total side length, surface area and volume of the cuboid below: 6%.
