...and placed in the other member with its sign changed. Hence, we say : A number may be transferred, or transposed, from one member of an equation to the other, provided its sign be changed. In the following equations, transpose the unknown numbers to the first member and the known...

...in the second member with its sign changed. Such change is called transposition. This rule follows : A term may be transposed from one member of an equation to the other if its sign is changed. Then, in solving, mx + c = b. Transposing c, mx = b — c, and dividing both...

...were taken from one member of the equation and placed in the other, with its sign changed. Rule. — A term may be transposed from one member of an equation to the other, provided its sign is changed. HISTORICAL NOTE. — Our word algebra, curiously, is associated with this process, transposition. About...
