Question

4+(−7) is units from 4 in the number line to find

4+(−7).

a) -3
b) -5
c) 3
d) 5

Answer 1

The addition of 4 and (-7) results in -3, after subtracting 7 from 4 and assigning the sign from the larger absolute value number (7) which is negative.

Step-by-step explanation:

The question asks to find the result of adding 4 and (-7) on a number line. When combining numbers with opposite signs, you subtract the smaller number from the larger one, and the sign of the result comes from the larger number. However, because we are adding a negative number, we move to the left on the number line from the positive number. The operation 4 + (-7) is equivalent to 4 - 7, which equals -3. Thus, the distance from 4 to 4 + (-7) on the number line is 3 units, but in the negative direction, making the answer -3.
