324 ⊕ 289
√324 + √289
18 + 17 = 35
441 ⊕ 484
√441 + √484
18 + 17 = 35
21 +22 = 43
Therefore,
625 ⊕ 400
√625 + √400
25 + 20 = 45
If - stands for division, + for multiplication, ÷ for subtraction, x for addition, then which of the following equations is correct?
20 - 4 + 6 ÷ 9 x 4 = 25
20 + 6 - 4 x 9 ÷ 6 = 32
20 ÷ 9 x 9 - 4 + 6 = 33
20 x 4 - 6 - 4 + 9 = 20

- means ÷, + means x, ÷ means-, x means +, then which of the following equations is correct?
43 x 7 ÷ 5 + 4 - 8 = 25
48 ÷ 5 + 8 x 10 - 2 = 13
36 x 4 - 12 + 5 ÷ 3 = 420
42 + 5 ÷ 6 x 8 - 3 = 28
