Question

The slection for 1. Is divide,subtract,multiply and add. And say the Awnser for the second one don’t just give me one Awnser ASAP

Answer 1

The basic principles for addition and subtraction involve following rules for handling positive and negative numbers. For multiplication and division, the answer's sign depends on the signs of the numbers being multiplied or divided. When two positive numbers add or multiply, the result is positive. When two negative numbers add or multiply, the result is also positive. When one number is positive and the other is negative, the result is negative.

Step-by-step explanation:

Addition and Subtraction:

1. When two positive numbers add, the answer has a +ve sign. For example, 3 + 2 = 5.
2. When two negative numbers add, the answer has a -ve sign. For example, -4 + (-2) = -6.
3. When two numbers with opposite signs add, subtract the smaller number from the larger number, and the answer has the sign of the larger number. For example, -5 + 3 = -2.
4. In subtraction, change the sign of the subtracted number and then follow the addition rules. For example, subtract 3 from 5:

Multiplication and Division:

When two positive numbers multiply, the answer has a +ve sign. For example, 2 x 3 = 6.

When two negative numbers multiply, the answer has a +ve sign. For example, (-4) x (-3) = 12.

When the two numbers multiplied have opposite signs, the answer has a -ve sign. For example, (-3) x 2 = -6 and 4 x (-4) = -16.
