W.A.L.T Use in Algebra the Order of Operations
1st Brackets
2nd Exponents
THEN Division and multiplication
LAST Subtraction and Addition
If you had an equation like this and you had to read it to the class it would be much easier to say X - to = 4 rather than empty box - 2 = 4
⬇
| − | 2 | = | 4 |
x−2=4
The X in this equation =6. You don't only have to use x, for different numbers you use different letters.
