The answer to this question is "numerical expression; it consists of operation symbols."
To determine this, let's break down the given expression j + 150 × 50 step by step:
1. Start with the operation of multiplication: 150 × 50. This operation involves two numbers, 150 and 50, and the multiplication symbol (×), making it a numerical expression.
2. The result of the multiplication, 150 × 50, is added to another number represented by the variable j. Again, this involves the addition symbol (+), making it a numerical expression.
3. Since both steps involve operation symbols (+ and ×) and numbers, the overall expression j + 150 × 50 can be classified as a numerical expression.
Therefore, the correct answer is "numerical expression; it consists of operation symbols."
The correct answer is:
"numerical expression; it consists of only numbers"
