If M and N denote two numbers, specify m ⁃ n = (n-m) × 5, and find the value of 3 ⁃ 4 ⁃ 6

If M and N denote two numbers, specify m ⁃ n = (n-m) × 5, and find the value of 3 ⁃ 4 ⁃ 6

You can first calculate 4 ⁃ 6 = (6-4) × 5 = 10, then 3 ⁃ 6 = 3 ⁃ 10 = (10-3) × 5 = 35

Let m and n be two numbers, and m ∧ n = 5 × n - (M + n) △ 2 (the meanings of +, -, ×, △ and brackets on the right side of the equation are the same as those in the usual four arithmetic operations), then 3 ∧ (4 ∧ 6)=______ ．

3 × (4 × 6) = 3 × [5 × 6 - (4 + 6) × 2] = 3 × [30-5] = 3 × [25 = 5 × 25 - (3 + 25) × 2 = 125-14 = 111; so the answer is: 111

One number is 6 times larger than 5 times of M, and the other number is 4 times smaller than 3 times of M. find the sum of the two numbers

A number is six times larger than five times M,
5m+6;
The other number is four times smaller than three times of M,
3m-4;
The sum of these two numbers = 5m + 6 + 3m-4 = 8m + 2;
