Literacy Research Memory Challenge Skill Working with directed number and negative numbers Literacy Research Memory Learn the negative six times tables so you can remember calculations such as -6 x 5 = -30 and -30 ÷ 6 = -5 with confidence Explain how you would help someone to understand what can be said to be different between a temperature of minus 3°C (-3°C) and the number negative 3 ( -3 ). Is zero a positive or a negative number? Is it possible to square root a negative number? Challenge Skill Q1. The formula for calculating the terminal velocity, v, of a body after an initial velocity, u, an acceleration, a, and after a given time, t, is v = u + at A car had an initial velocity of 28 m/s, over a time of 5 seconds the mean average rate of acceleration was -3m/s2 What is the terminal velocity of this car after the five seconds? Q2. Find out about another formula used in another subject area that could need negative values to be substituted into it. Show an example of the formula being used with a negative value for one of the variables. 1. Evaluate the following without using a calculator a) -6 + - 9 b) 2 + - 7 c) 5 - - 8 d) (-5)2 e) -8 - - 4 f) -72 ÷ 9 g) 8 × (-3.25) h) -6.4 ÷ 8 i) -7 – (+26) j) -7 × -3 k) (-4)3 Two numbers sum to -8 and multiply to make -20, what are the two numbers? Five numbers have a mean average of 6 and a median of 4, two of the numbers are negative. What could the five numbers be? 4. a) The temperature is 4˚C. It rises by 5˚C. What is the new temperature? b) The temperature is -2˚C. It rises by 6˚C. What is the new c) The temperature was 12˚C and is now -3˚C. What is difference between these two temperatures?
