Tìm x:
a) 28 – x = 16
34 – x = 9
34 – x = 15
b) x – 14 = 18
x + 20 = 36
17 – x = 8
Tính nhẩm:
6 + 9 = ... | 30 + 40 = ... |
7 + 9 = ... | 80 − 60 = ... |
8 + 9 = ... | 50 + 30 = ... |
9 + 9 = ... | 90 − 30 = ... |
300 + 300 = ... | 15 − 8 = ... |
600 − 300 = ... | 16 − 8 = ... |
700 + 200 = ... | 17 − 8 = ... |
900 − 700 = ... | 18 − 9 = ... |
