$$m\div10$$

$$10\ m$$

$$10m$$

$$10\div m$$

product of 3 and y

sum of 3 and y

difference of 3 and y

3 divided by y

n - 2 = 52

2 - n = 52

52 - n = 2

n - 54 = 2

x - 12 = 3

3 - x = 12

12 - x = 3

x - 3 = 12

x + 10 = 10

x - 10 = 20

x = 10 + 20

x + 10 = 20

$$5\ +\ n\ =\ 25$$

$$5\ -\ n\ =25$$

$$5n\ =\ 25$$

$$5\div n\ =\ 25$$

2n - 1

1 - 2n

n - 2 - 1

1 +2 - n

n + 16 = 26

n - 16 = 26

n + 16 = -26

n - 16 = -26

$$4x=60$$

$$x=60$$

$$\frac{1}{4}x\ =\ 60$$

$$60\ x\ =\ 4$$

$$2x=346$$

$$x+2=346$$

$$x-2=346$$

$$x\ \div\ 2\ =\ 346$$

x + 176 = 34

x - 176 = 34

x + 34 = 176

x - 34 = 176
