Find the value of 3a − 2b, when a = 8 and b = 10

If a = 3, b = 0, c = 2 and d = 1, find the value of abc − bcd + cda

Evaluate:

(23 – 15) + 4

Simplify:

x + y − (x + `overline("y"-"x"))`

Fill in the blank:

5a + 4b + 4x − 2c = 4x − (...........)

Insert the bracket as indicated:

a + 4b − 4c = a + (...............)

Insert the bracket as indicated:

a − 3b + 5c = a − (..............)

If x = 3, y = 2 and z = 1; find the value of y² – x² + 6z²

If x = 3, y = 2 and z = 1; find the value of xy + y²z – 4zx

Multiply and then evaluate:

(4x + y) and (x – 2y); when x = 2 and y = 1.
