Negative 5, here they're subtracting a 5, so that . Arithmetic Simplify: (6+3)\cdot (10-7) (6+3)(10 7) See answer Negative numbers Simplify: \frac {-4} {9}-\frac {3} {-6} 94 63 See answer Linear inequalities 1 Solve for x: x-4\ge-6 x4 6 See answer Powers and roots 1 Simplify: \sqrt {36} 36 See answer Fraction Simplify: \frac {3} {10}+\frac {6} {10} 103 + 106 See answer In other words, 6 - -3 is 9. Now, let's look at this one. I definitely select this one. If you subtract a negative 3, that's the same thing as adding a 3.

Well, it depends on what the negative number is. . 6 - 3 are two positive numbers. Algebra 1 Course: Algebra 1 > Unit 7 Lesson 1: Checking solutions of two-variable inequalities Testing solutions to inequalities Solutions of inequalities: algebraic Solutions of inequalities: graphical Testing solutions to systems of inequalities Math > Algebra 1 > Inequalities (systems & graphs) > Checking solutions of two-variable inequalities One plus and one minus make . Multiplying and dividing negatives are the same because there is no difference between those sides of zero except the side of zero. For example: If you have $5 in your bank account and you spend $7, you have $0, but you also owe $2. Draw a long, horizontal line. 5 - 3 = 2.

Calculator Use Add, subtract, multiply and divide decimal numbers with this calculator. 1 + 1 = 2 51 + 32 = 83 -14 + (-6) = -20 -196 + (-71) = -267 Notice that equations with two positive numbers have positive sums, and equations with two negative numbers have negative sums. For example, in 5+ (-7), since the number 7 is greater than 5, you take away more than you have, so you then have a negative amount. If you are dealing with integers, multiplying by positive integers actually means "repeating addition for N times" so you are doing ( A) + ( A) + ( A) + ( A) + and it will give you a negative number since it persistently go to negative direction.
