5. 373 875 x Start with the ones. Do a 'SPRAY'. Multiply and "CARRY" - Just like addition! 5 1 6 3 18 Now do the tens- Use a 'SPRAY'! First, we must put a place holder under the ones. 0 Erase your "carried" numbers so you dont get confused. 1 2 1 5 26 Now let's do the hundreds using a "spray". Erase your "carried" numbers so you dont get confused! We must put place holders under the ones and tens. 0 0 4 2 8 5 29 Now add! + 5 7 3 1 6 1 2 1 3
