i have a question on a math problem,
please#1 explain why 7*8 is not a number sentence. Next question is write two true number sentence.
thank you!
7 * 8 isn't complete.
7 * 8 = 56 is a complete sentence.
I'm sure you can write two true number sentences now.
24,_,48,_72,_ rule:
To answer your first question, a number sentence is a mathematical statement that includes numbers and mathematical operations. However, "7*8" is just a multiplication expression, not a complete number sentence, because it lacks an equal sign or a relational operator.
To write two true number sentences, here are some examples:
1. Addition: 3 + 4 = 7
In this number sentence, the operation is addition (+), and the numbers 3 and 4 are added to get a sum of 7.
2. Subtraction: 9 - 5 = 4
In this number sentence, the operation is subtraction (-), and 5 is subtracted from 9 to get a difference of 4.
Remember, a number sentence needs to include an equal sign or a relational operator, like greater than (>), less than (<), greater than or equal to (≥), or less than or equal to (≤).
