Question

Evaluate the following numerical expressions.

6+3.4=
(6 + 3) ÷ (4 − 5) =
0
6+2³-3=
4

Answer 1

To evaluate numerical expressions, perform the required mathematical operations according to the given order of operations.

Step-by-step explanation:

To evaluate the first expression, simply add 6 and 3.4 together. 6 + 3.4 = 9.4.

To evaluate the second expression, follow the order of operations (PEMDAS). First subtract 5 from 4 to get -1, then divide 6 + 3 by -1. This gives us -9.

To evaluate the third expression, start with 2 cubed which is 8, then add 6 and subtract 3. So, 6 + 2³ - 3 = 8 + 6 - 3 = 11.
