Praxis 5025 Math (2023/2024) Already Graded A Properties of addition Commutative property associative property additive identity property distributive property Commutative property When two numbers are added, the sum is the same regardless of the order of the ad in. Example 4+2 = 6 2+4 = 6 Associative property When three or more numbers are added, the sun is the same regardless of the grouping of the advance. Example (2+3)+4=2+(3+4) Additive identity property The sum of any number and zero is the original number. Example 5+0 = 5 0+5 = 5 Distributive property The sum of two numbers times a third number is equal to the sum of each ad in times the third number. Example 4*(6+3)=4*6+4*3 Subtracting negative and positive integers If both sides are positive the answer will be positive. 8-(-4)=12 8+4=12 If both sides are negative, the answer will be negative. -8-(-4)=-12 -8-4=-12 If the signs are different, subtract the smaller absolute value from the larger absolute value. The sign will be the sign of the integer that produced the larger absolute value. 6-(+2)=6-2=4 -6-(-2)=-6+2=-4 6-(-2)=6+2=8 -6-(+2)=-6-2=-8
