6th Bronte & 6th Neruda

Quote: Better a diamond with a flaw than a pebble without.- Confucius.

Objective: Use order of operations.

Activate Prior Knowledge:

Solve.

  1. 3 + (9 + 7)=
  2. (7-3) + 4=
  3. 4 x (2 + 5)=
  4. (9 - 2) x 7=

New Knowledge:

To evaluate an expression that contains more than one operation you use rules called order of operations.

We use PEMDAS to remember the operations:

P: parenthesis

E: exponents

M: multiplication

D: division

A: addition

S: subtraction

Multiplication and division is always the first operation from left to right.

Addition and subtraction is always the first operation from left to right.
