Math Knowledge Check - November 3rd

When we talk about integers, positive numbers are represented by: weights balloons a basket When we talk about integers, negative numbers are represented by: weights balloons a basket When we talk about adding and subtracting integers, our overall total is represented by: weights balloons a basket Subtracting a negative (removing weights) is the same as: Adding a positive Adding a negative Subtracting a positive Subtracting a positive (removing balloons) is the same as: Adding a positive Adding a negative Subtracting a positive When you multiply or divide two numbers with the same sign (- x -) or (+ x +)your answer will be: positive negative zero When you multiply or divide two numbers with a differentsign(+ x -) or (- x +)your answer will be: positive negative zero Adding Integers Write each answer in this format (-4) If you do not include the brackets AND the sign, your answer will be counted as incorrect. The only exception is 0, which you simply write as 0. (-12) (-4) (+14) (+3) (-4) (+20) (+45) (-8) (-35) Subtracting Integers Write each answer in this format (-4) If you do not include the brackets AND the sign, your answer will be counted as incorrect. The only exception is 0, which you simply write as 0. (-18) (+22) (-16) (-20) (+17) (-10) (-1) (-9) 0 Multiplying Integers Write each answer in this format (-4) If you do not include the brackets AND the sign, your answer will be counted as incorrect. The only exception is 0, which you simply write as 0. 0 (-16) (+21) (+40) (-60) (-30) (+15) (+15) Dividing Integers Write each answer in this format (-4) If you do not include the brackets AND the sign, your answer will be counted as incorrect. The only exception is 0, which you simply write as 0. (-4) (-2) (+1) (-3) (+3) (-7) (+4) (-2) Exponential Notation Write each multiplication sentence as an exponent. If you want to write (34), use this format: 3^4 6^5 2^7 31^6 3^4 9^2 14^3 Expanded form Write each as a multiplication sentence. Please do not put spaces between any of your numbers and operation symbols. 8x8x8x8 4x4x4x4x4x4x4x4x4 13x13 100x100x100x100x100x100 Squaring Numbers Show how to square the number 4 using a diagram, numbers, symbols, and words.
