how do i do these

(5+4) times 7

4 + 6 x 3

Follow the order of Operations:

Parentheses, Exponents, Multiplication and Division, Addition and Subtraction.

(5+4) *7. Evaluate within the parentheses first (5+4) = 9 then multiply by 7 to get 9 * 7 = 63

4 + 6 * 3 . Multiply 6*3 first, then add 4

(3+5) * 5 + 1 - Evaluate within the parentheses first, then multiply by 5, then add 1

4[30 - (10 - 2) * 3] : Start with your innermost parentheses (10 - 2) and evaluate. Multiply this result by 3. Then subtract from 30. Now that everything in the brackets is done, multiply by 4.

[8*2 - (3+9)] + [8 - 2*3]

Start with inner parens first, then rewrite:

[8*2 - 12] + [8 - 2*3]

Now multiply within the parens:

[16 - 12] + [8 - 6]

Subtract within the brackets:

[4] + [2]

Remove the brackets and add to get a result of 6
