Option 1
- Find the value of the expression:
324 + 189 – 205 + 18 =
56 : 7 * 3 : 4 =
180 – 81: 9 + 6 * 4 =
16 : (15 – 11) + 48 : 8 =
- Compare the expressions:
3* 8 – 20 : 4
(3 *8 – 20) : 4
30 + 36 + 4
30 + (36 + 4)
12 : (6 * 2)
12 : 6 * 2
- Insert the signs of the equations to make a valid equality:
2 6 3 = 4
- Solve the problem:
The canteen used up 18 kg of rice and half as much buckwheat as rice. The number of millet used is the same as the number of rice and buckwheat. How many kilograms of millet were used?
- Solve the equations:
X + 315 =582
72 : Y = 8
Option 2
- Find the value of the expression:
415 – 226 + 107 – 29 =
63 : 7 * 2 : 6 =
72 : 9 + 319 – 8 * 7 =
3 * (6 + 3) – 36 : 6 =
- Compare the expressions:
(3* 6 – 8) : 2
3 * 6 – 8 : 2
20 + 17 + 3
20 + (17 + 3)
16 : 4 * 2
16 : (4 * 2)
- Insert the signs of the equations to make a valid equality:
4 4 4 = 12
- Solve the problem:
