HELP PLEASE and help me understand
const2013 [10]

When subtracting a number from a negative (like question one) the subtraction sign will now be an addition sign.

1.

6-(-7)=13

For question 2, its simple subtraction. If you subtract a negative from positive, it'l be a negative.

2.

-3 - 3= -6

3.

-15 - 23 = -38

Now we combine my previous explanations. Subtracting a negative from a negative will be like adding (like in question 4)

4.

-9 - (-5)= -4

5.

5 - (-15)=20

6.

78-(-17)=95


Extra Info:

When adding a number (doesnt matter if positive or negative) to a negative it will turn into subtraction.

Examples:

6+(-9)=-3

-9+(-9)= -18

What is a square root and what does it do?
WINSTONCH [101]

Answer:

Hey

Definition:-

A square root is a number which produces a specific quantity when multiplied by itself.

Example:-

Suppose the area of a square of side 6 cm is given by 6 × 6 = 36 cm².

Therefore 36 is said to be the square of 6. We write 6² = 36 and we read the ‘the square root of 6 is 36' or simply ‘6 squared is 36.'

hope this helps
