It doesn&#8217;t matter what the number is, when you multiply it to zero, you get zero as the answer.<\/p>\n<p>&nbsp;<\/p>\n<p>Question 2.<br \/>\n________ says that 1 times any number is that number.<br \/>\nAnswer:<br \/>\nThe Identity (One) Property of Multiplication says that 1 times any number is that number.<br \/>\nExplanation:<br \/>\nThe identity property of 1 says that any number multiplied by 1 keeps its identity. The reason the number stays the same is because multiplying by 1 means we have 1 copy of the number.<\/p>\n<p>&nbsp;<\/p>\n<p>Question 3.<br \/>\n_________ says that you can multiply factors in any order, and the product stays the same.<br \/>\nAnswer:<br \/>\nThe Commutative (Order) Property of Multiplication says that you can multiply factors in any order, and the product stays the same.<br \/>\nExplanation:<br \/>\nThe math rule that says the order in which we multiply the factors does not change the product is the commutative property.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Multiplying Use multiplication to solve.<\/strong><\/p>\n<p>Question 4.<br \/>\n10 \u00d7 1 = ________<br \/>\nAnswer:<br \/>\n10 \u00d7 1 = 10.<\/p>\n<p>Question 5.<br \/>\n2 \u00d7 10 = _______<br \/>\nAnswer:<br \/>\n2 \u00d7 10 = 20.<\/p>\n<p>Question 6.<br \/>\n0 \u00d7 5 = _______<br \/>\nAnswer:<br \/>\n0 \u00d7 5 = 0.<\/p>\n<p>Question 7.<br \/>\n9 \u00d7 5 = _______<br \/>\nAnswer:<br \/>\n9 \u00d7 5 = 45.<\/p>\n<p>Question 8.<br \/>\n2 \u00d7 7 = _________<br \/>\nAnswer:<br \/>\n2 \u00d7 7 = 14.<\/p>\n<p>Question 9.<br \/>\n1 \u00d7 8 = _______<br \/>\nAnswer:<br \/>\n1 \u00d7 8 = 8.<\/p>\n<p>Question 10.<br \/>\n5 \u00d7 7 = ?<br \/>\nA. 7 + 5<br \/>\nB. 5 + 7<br \/>\nC. 7 \u00d7 5<br \/>\nD. 7 \u00f7 5<br \/>\nAnswer:<br \/>\n5 \u00d7 7 = 35.<\/p>\n<p>Explanation:<br \/>\n5 \u00d7 7 = ?<br \/>\n=&gt; 5 \u00d7 7 = 35.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Adding 2-Digit Numbers<br \/>\n<\/strong>Find the sum.<br \/>\nQuestion 11.<br \/>\n16 + 12 = _______<br \/>\nAnswer:<br \/>\n16 + 12 = 28.<br \/>\nExplanation:<br \/>\n16 + 12 = ??<br \/>\nTen&#8217;s place: 2+1=3.<br \/>\nOnes place: 6+2=8.<\/p>\n<p>&nbsp;<\/p>\n<p>Question 12.<br \/>\n21 + 14 = _______<br \/>\nAnswer:<br \/>\n21 + 14 = 35.<br \/>\nExplanation:<br \/>\n21 + 14 = ??<br \/>\nTen&#8217;s place: 2+1=3.<br \/>\nOnes place: 1+4=5.<\/p>\n<p>&nbsp;<\/p>\n<p>Question 13.<br \/>\n24 + 12 = _______<br \/>\nAnswer:<br \/>\n24 + 12 = 36.<br \/>\nExplanation:<br \/>\n24 + 12 = ??<br \/>\nTen&#8217;s place: 2+1=3.<br \/>\nOnes place: 4+2=6.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Arrays<br \/>\n<\/strong>Question 14.<br \/>\nHow can you represent 3 \u00d7 6 using an array?

The Commutative property\u00a0of addition is written as: A + B = B + A.<br \/>\nThe\u00a0distributive property\u00a0tells us how to solve expressions in the form of a(b + c). The\u00a0distributive property is sometimes called the distributive law of multiplication.<br \/>\nThe \u00a0identity property of 1 says that any number multiplied by 1 keeps its identity . In other words, any number multiplied by 1 stays the same. The reason the number stays the same is because multiplying by 1 means we have 1 copy of the number<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Write T for true or F for false.<br \/>\n<\/strong>Question 5.<br \/>\n______ 3 and 8 are multiples of 24.<br \/>\nAnswer:<br \/>\n___T___ 3 and 8 are multiples of 24.<\/p>\n<p>Explanation:<br \/>\n3 \u00d7 8 = 24.<\/p>\n<p>Question 6.<br \/>\n________ You can multiply factors in any order.<br \/>\nAnswer:<br \/>\n___T_____ You can multiply factors in any order.<\/p>\n<p>Explanation:<br \/>\nTrue you can multiply factors in any order.<br \/>\nExample:<br \/>\n3 \u00d7 8 = 24.<br \/>\n8 \u00d7 3 = 24.<\/p>\n<p>&nbsp;<\/p>\n<p>Question 7.<br \/>\n________ The product of zero and any number is that number.<br \/>\nAnswer:<br \/>\n___F_____ The product of zero and any number is that number.<\/p>\n<p>Explanation:<br \/>\n0 \u00d7 2 = infinity.<br \/>\n2 \u00d7 0 = 0 or Zero.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>Question 8.<br \/>\n________ There are 3 factors in the equation 5 \u00d7 3 \u00d7 2 = 30.<br \/>\nAnswer:<br \/>\n____T____ There are 3 factors in the equation 5 \u00d7 3 \u00d7 2 = 30.<\/p>\n<p>Explanation:<br \/>\n2 \u00d7 15 = 30.<br \/>\n3 \u00d7 10 = 30.<br \/>\n5 \u00d7 6 = 30.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Use Vocabulary in Writing<\/strong><br \/>\nQuestion 9.<br \/>\nExplain how to use 8 \u00d7 5 = 40 to find 8 \u00d7 6.
